Hi,

I got all the way through this so thanks for the walk through! I run "rails server -b 0.0.0.0" and the server boots fine but when I go to localhost:3000 in the browser, the browser icon spins but the server does not respond. Has anyone seen this before?

I've worked it out now. It seems that thin was the problem. I switched to webrick and the app now runs perfectly. I don't exactly no what the problem was with thin but this solution works for now!

So cool. I have been waiting for you to write this :)

This is great tut- based on it I installed rails 5 and ruby 2.3.1. created new test app and after rails -s I have something like this: => Booting Puma
=> Rails 5.0.0 application starting in development on http://localhost:3000
=> Run `rails server -h` for more startup options

Any ideas what should I do ?

I get the error like : `sudo: setresuid() [1000, 106, 1000] -> [-1, 0, -1]: Operation not permitted` when I try to create new postgres user. Is it going to be fix in the nearest feature?

How were you able to get the terminal to let you copy the SSH key so that you could paste it into GitHub? Copy and paste is not working for me using shortcuts or the mouse, and there is no menu that I can see.

I run Rubinius on Windows 10 Bash.

When I run "rails new testApp -d mysql" I get back
"Errno::ENOMEM: Cannot allocate memory - sudo -p "

Your user account isn't allowed to install to the system Rubygems."

Anyone have any ideas where I went wrong?

Fixed it - had to do a fresh install of everything from outside of the firewall at my office.

Tried re-installing and now the error I get is
"Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

current directory: /home/barp/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/debug_inspector-0.0.2/ext/debug_inspector

Cannot allocate memory - /home/barp/.rbenv/versions/2.3.1/bin/ruby -r ./siteconf20160805-549-tt92si.rb extconf.rb 2>&1"

I received an error "There was an error while trying to load the gem "uglifier". Gem Load Error is: Could not find a JavaScript runtime." Any ideas?

After I close the terminal I lost all the settings that I had installed following this tutorial. I will try install it again but I fear that the same happen again. What should I do to prevent it?

I'm able to go through this whole tutorial for Windows 10 bash and get everything listed here working (using rvm currently). I get through all the final steps without error, got a working server, etc...

But I'm trying to follow a basic "hello world" tutorial ( found here: http://iridakos.com/2013/11... ) and when I try "rails generate controller pages" I get: "Error: Command 'rails' not recognized" as well as an info section on "Usage: spring COMMAND [ARGS]" and "Usage: rails COMMAND [ARGS]"

I'm confused as to how it could possibly say 'rails' is not recognized. I can do "rails -v", I can do "rails new", I can do "rails server", etc...

Anyone have any advice? I've tried this like 6 times now (resetting my entire linux subsystem after each failed try) using both rvm and rbenv and I end up stuck at this point every time. Any pointers as to where I'm going wrong would be greatly appreciated...thanks!

THIS IS AMAZING!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I love you <3

Excellent!! Thanks so much for this. Up and running without a hitch after first updating to Windows 10 Anniversary. You don't need to be an Insider to update now.

I hope WSL is the real deal...I've had several fits and starts trying to get going with rails on a windows machine.

Suggestion for newbies: rather than create myapp in your linux directory, switch to your windows directory, then create myapp there.

At that point you'll have ready access to work on the myapp files via your IDE

Thus, for final step, type this at the prompt $: cd /mnt/c/Users/you

Then in this director type $: rails new myapp

Got things rolling smoothly with this article. Not sure if anyone else had this issue but ruby took a really long time to install. I thought it was hanging but figured I'd give it a chance and left it running when I went to bed. In the morning it was done so slightly longer than 45 minutes for me!

I installed everything. Started the server. Went to the webpage and I got the error:
Cannot load `Rails.application.database_configuration`: No such file or directory @ rb_sysopen - /home/dale/myapp/config/database.yml

Also I tried a cat config/database.yml and received a no file or directory error.

I look in the directory and the file is there.

Frustrating. Can't find a solution. Anyone?

Thank you! I would suggest to add to postgresql installation quide, that it is possible to make it running by installing postgres directly on windows (https://www.postgresql.org/... - prefferably version 9.3.

Another issue I had is with Thin rails server. You have to use webrick by setting enviroment variable: `export RACK_HANDLER=webrick` and then run `rails s`

PS: I am going to try to develop our application on windows with this setup, I will post my experience then. Our application is for chess players and tournament organisers - https://www.swips.eu

Unfortunately as of now, when running "sudo -u" there is a bug in the Windows Bash which states: `sudo: setresuid() [1000, 1000, 1000] -> [-1, 0, -1]: Operation not permitted`

Official bug here: https://github.com/Microsof...
Of course you can work around that by using `sudo su USER`.

Otherwise a really nice tutorial with good hints (especially the `chmod +t -R ~/.bundle` one)! Million thanks!

I seem to have trouble sending http requests from my rails server on my windows 10 ubuntu subsystem, whereas people working on their OSX or normal linux have no such problem even with the same code. I keep getting a Net::OpenTimeout (expiration expired) exception no matter what type of http request I do. Has anyone experienced this as well and does anyone know why this might be happening?

@petertruchan:disqus How exactly did you get the postgresql installation to work? I followed the instruction i found here: https://github.com/Microsof... but it didn't work. Any tips/comments would be appreciated. Thanks

Hi!. I have a problem running a rails server. It's seems that a Thin Server is up and running, but not listening on port 3000

This picture will show you my situation. Please help me!.

hey .. did all the things till the final step /

Brilliant - all worked v smoothly, like someone else said installing ruby 2.3.1 took ages. You may also need to install rmagick - to do this type sudo apt-get install libmagickwand-dev imagemagick

I got the problem, i'm following your tutorial, but this result after running rails new myapp -d mysql

There was an error while trying to write to
`/home/user/.bundle/cache/compact_index/rubygems.org.443.29b0360b937aa4d161703e6160654e47`.
It is likely that you need to grant write permissions for that path.
run bundle exec spring binstub --all
bundler: command not found: spring

so how do we find the root directory where all the created apps are located?

Any ideas how to access that Ruby binary from Windows? For example, how do I use it as the RubyMine Ruby.

Serving static files with webrick inside WSL seems to be as slow as it was on Windows. Have anybody experience this? any solutions?

please explain to me, i still don't understand, why we don't install rails just using railsinstaller, or some simple easy installer else,,

I believe this guy actually reuses some other people's article and copy pasted.After installing ruby-build, when you do an rbenv install a specific version, Bash on Windows cannot create directories for installing the ruby version.

After installing everything correctly, I received a "This site can't be reached" error for localhost:3000

Any suggestions?

ALERT !
© If you're using Windows Subsystem for Linux then there are currently some limitations on file system notifications that mean you should disable the spring and listen gems which you can do by running rails new blog --skip-spring --skip-listen.

I know this is a bit of an older post, but it is one of the few places where someone is doing, more or less, what I'm trying to do. My question is, has anyone successfully done this with jruby? I have tried installing jruby 9000 in my home directory, in the multi-user setup (usr/bin/jruby which are symlinks pointing to /usr/lib/jruby/bin), and using RVM in the home directory. In all cases I get to the point where jruby is installed and seems to run properly, but the gem command simply doesn't work. When I try to run "gem install rails" or "gem install bundler" or "jruby -S gem install..." I get "Unable to download data from https://rubygems.org/ - timed out"

is it possible to use sublime text somehow? Just wondering

Thanks for this.. It was quite helpful.

As for now this Bash is open for every PC with 64-bit Windows 10 Anniversary Update build 14393 (1607) or later - https://msdn.microsoft.com/...
So I install Ruby 2.4.1 from sources (and run Jekyll 3.4.3).

Incase you're not able to do rake db:migrate with pgsql try this .

I installed pgsql on local windows and not on ubuntu bash
Then did the following:
Go to you config/environments/development.rb and comment out The Line config.file_watcher = ActiveSupport::EventedFileUpdateChecker,
After this run - rails s or rake db:migrate.

This worked for me and is pretty fast too.
Earlier I was using Vagrant (VM) and this (Ubuntu on bash) is faster than vagrant method,
Just my opinion, Hope it helps :)

It looks like this does not work currently if you've been upgraded to xenial. Specifically, ruby does not appear to install correctly if you close the bash session, and you have to rerun the rvm script every time, in addition to not being able to install the rails gem at all.

When going to locahost:3000 in the browser I get, json response as it it a api:

{"status":500,"error":"Internal Server Error","exception":"#\u003cRuntimeError: Cannot load `Rails.application.database_configuration`:\nCould not load database configuration. No such file - [\"config/database.yml\"]\u003e

I have one problem on install postgresql on create user.
here is command:
malin@XMAN:~$ sudo -u postgres createuser malin -s
output: sudo: unable to resolve host XMAN
output: sudo: setresuid() [1000, 106, 1000] -> [-1, 0, -1]: Operation not permitted
how can I fixed it? Thank you.

Hi,
can you do a tutorial to explain how it's possible to configure rubymine to edit a project? (project in ubuntu /home/User). I would like to use Rubymine i have install on windows to edit code in ubuntu subsysteme.

Thanks a lot!

Chris it would be interesting to update the tutorial for Windows 10 Creators Update considering the many new updates and improvements the Windows Subsystem for Linux has received! ;) https://blogs.msdn.microsof...

My install works fine until 'gem install bundler' when I get this error:'/home/james/.rbenv/versions/2.4.0/bin/ruby: symbol lookup error: /home/james/.rbenv/versions/2.4.0/lib/ruby/2.4.0/x86_64-linux/socket.so: undefined symbol: parse_numeric_port'.
I'd appreciate any help as I really want to get WSL to work.

Hello,

Thanks for the tutorial. It really helped me to get my basic setup up and running.
Thou I did have to fiddle around to get a few things working.
I should note that 5/14/17 I was not able to do

sudo -u postgres createuser YOURUSER -s

instead I had to use

sudo sudo -iu postgres createuser YOURUSER -s

due to -u not working at the time on WSL. Also I had to start the postgresql service before creating the user with

sudo service postgresql start

Hope this comments help people trying to install it later.

Thanks again for all your help and to all the RoR community, I just spent the last few days until I had my successful attempt at installing everything I wanted on WSL (yeah there were 4, I am now familiar with lxrun.exe /uninstall /full and lxrun.exe /install to reset the entire linux subsystem :P).

PS:
I would like to see added to the tutorial some information on installing MongoDB. For the moment I will just leave the link to the official tutorial https://docs.mongodb.com/ma... small comment though there are problems starting mongodb as a service so for now the only way I have found is to use sudo mongod. Also, remember to run mkdir /data/db before starting the database (that last bit is required but it is not included in the official tutorial from mongo).

The source on my machine does not have the same path ~/.rvm/scripts/rvm

Mine is @: /usr/local/rvm/scripts/rvm

Also, The source is not persisting after exiting the terminal. And finally, it's failing when I try to start the rails server.

edit: got it working in the end, lots of patience required :)

Hello, thanks for the tutorial, however, I'm just trying to install rbenv and it has already taken 1 hour of waiting, it seems it is stuck on 'installing ruby-2.4.0...'. Should I just cancel and start afresh with rvm?

I just want to share how I was able to install postgresql 9.5.
First, after running "sudo apt-get install postgresql-common postgresql libpq-dev" I got the error:

"http://archive.ubuntu.com/u... xenial-updates/main amd64 postgresql-client-9.5 amd64 9.5.7-0ubuntu0.16.04 Hash Sum mismatch"

So, as the console sugested, I executed it again adding "--fix-missing" and it worked.

Next, running "sudo sudo -u postgres createuser username -s" throwed the error:

"psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?"

which I solved by running "sudo pg_ctlcluster 9.5 main start".

Finally, trying to run "rails db:create" I got the error:

"new encoding (UTF8) is incompatible with the encoding of the template database (SQL_ASCII)"

The solution for this was running:
- sudo sudo -u postgres psql
- UPDATE pg_database SET datistemplate = FALSE WHERE datname = 'template1';
- DROP DATABASE template1;
- CREATE DATABASE template1 WITH TEMPLATE = template0 ENCODING = 'UNICODE';
- UPDATE pg_database SET datistemplate = TRUE WHERE datname = 'template1';
- \c template1
- VACUUM FREEZE;

I found all the above solutions searching in Google, but I don't remember the links.

Hope it helps someone and saves them some time.

I have mysql installed on windows. Do I need to install it separately on Linux Subsystem?

How old is this guide? I ask because, as of 6/22/2017 msdn quotes:
"Languages: Javascript/node.js, Ruby, Python, C/C++, C# & F#, Rust, Go, etc.
Services: sshd, MySQL, Apache, lighttpd,"

Suggesting that ruby should have full support now?

Thanks for the tutorial!

Just a note, it's "without further ado", not "without further adieu" 😉

ruby-build: definition not found: 2.4.0 ??? help me plz

I get this error anytime i start the rails server or type rails -v

Great post. The install went fine, including the MySQL server installation, but when I try to connect to the MySQL server, I get the message: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

I uninstalled it (sudo apt-get remove mysql-server) and re-installed. Same error message

If I try to re-install, I get the message that the MySQL server is already installed and is the latest version. Any ideas?

i got a q. now i am o root@laptop. does this mean i am on a vertual & so i can not get actual folders and files?

Is it possible to share folders like vagrant?

I get following error. I followed everything as mentioned in the article.
Looks like mysql db is not created.
Missed any step?

how to open Sublime, and point them to your folders in C:\code

It's very sloooow. Did anybody get this issue with all Rails/Rake commands?

Good post.

I also needed to run the following, prior to installing ruby:
sudo apt-get install -y gcc libssl-dev libreadline-dev zlib1g-dev make

I installed ruby and rails correctly, but when I run my new rails app, my browser cannot connect. I must have missed something obvious somewhere. Has anyone else had this problem?

Nothing wrong! Just had to start the MySQL service: "sudo service mysql start"

Is there anything wrong with just running `sudo apt install rbenv` instead of the shell script? I was having issues with the script. Only the plugins folder was cloned...

Doesn't work with me.

Just wanted to let you know that I just got this up and running! Thankfully I didn't have any issues. Thank you to whoever for putting this together! Great job!!!!

Alberto, yep. You'll always need libpq-dev to compile the C extension for Ruby to talk to Postgres. 👍

Hey John, not sure why that command doesn't work from you. I just pasted in the RVM installation instructions from their website. I don't use RVM though but as long as you get the gpg keys imported, that's all you need.

Hi,

I just impressed, awesome tutorial.

I love this tutorial.

Thanks

Hey all,
So I got this running a long time ago and haven't had any issues since but now when I run any rails command I get a warning that says:
/home/user/.rbenv/versions 2.5.3/lib/ruby/gems/2.5.0/gems/railities-5.2.2/lib/rails/app_loader.rb:53 warning: Insecurable world writeable dir mnt/c/rails/project

All the stackoverflow answers are to chmod go-w /home/user but this and many derivations of this doesn't work. What else can I try?

@eliot I looked into this a few months ago and just accepted that it wasn't going to go away unless WSL was changed by Microsoft. Details at: https://github.com/Microsoft/WSL/issues/1426.

There appears to be ways to get rid of it but could introduce a security issue... I decided it was probably a bit of OCD on my behalf and to just let it go. I just find chasing these bugs means hours lost where I could actually be writing code. If you do figure out a good way please tell though.

Hi, im using Windows 10 with the WSL, and im trying to set the Ruby Interpreter in RubyMine to the one i install using Chirs guide, using the following route /home/tensai/.rbenv/shims/ruby, the problem is that when it starts to Loading the Enviorment throws a Communication Error?

Can anyone tell how i can properly set my RubyMine to use the ruby install in WSL? using rbenv as the version manager.

Hey having a hard time debugging an error maybe someone has some insight?

this insecure world writeable dir has been plaguing me if I try to set up a DB and run rake db:create or rails db:create it wont allow it to do anything any help is appriciated!

Hey Chris I'm getting the following error:

Hi, can anyone help me with a problem, I'm using windows 10 I have installed ruby, Ubuntu and WSL. Whenever I run my code in visual studio editor or console, I receive this warning message,
warning: Insecure world writable dir /mnt/c in PATH, mode 040777
Is there any way I can fix the problem?

i have the same problem:
i tried an older version of bundler still no change.
then i've seen this :
gem install bundler -v 2.0.1

so i think that your solution chmod +t -R ~/.bundle is not good in my case,
error
chmod: cannot access '/home/cod/.bundle': No such file or directory

any idea for an work around?
thank you

Hi Chris,
when I do 'cd'=> and after 'pwd' => home/user_name,
therefore should i change the commands from:
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec $SHELL
to:
echo 'export PATH="$HOME/user_name/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec $SHELL
???

Hey there! This guide was VERY useful, as every other guide on the subject I found had untold errors along the way. This one worked perfectly, up one of the very last steps after installing postgresql, where you select it using this:

rails new myapp -d postgresql

I receive this error:

rake db:create

I receive this error:

Apologies for the long help request! I'm just starting out in coding, and getting my development environment set up on Windows is taking a good chunk of my time by itself unfortunately.

Hi, it's a great guide! I got through all steps successfully.
However, when I tried to create a newapp, I got the following error.

error: chmod on /mnt/c/code/.git/config.lock failed: Operation not permitted
fatal: could not set 'core.repositoryformatversion' to '0'

I already made sure the folder is writable.

Thank you!

It's no longer possible to install bash using the bash command, now you need to install a linux distribution via the Microsoft App Store

https://www.howtogeek.com/249966/how-to-install-and-use-the-linux-bash-shell-on-windows-10/

details in the link above

I was having the same problem as Alison Y. The solution for me was to remake the code directory using the "-p" option.

I believe curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash - should be changed for curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -

on WSL 1 (and WSL 2), rake running inside linux cant connect to postgresql running in windows through a unix domain socket. Instead you will need to connect using regular network over TCP/IP.

first, you need to determine your windows ip address. You can find this by looking in windows network settings; or by running ipconfig in powershell. In your linux, ipconfig.exe | grep IPv4 | cut -d: -f2 should work as well.

next in your rails cofig/database.yaml, uncomment the #host 127.0.0.1 line and change it to your ip address. Also, update the username, password, and port as necessary. (did you create the user in postgresql?)

for example:

...
development:
  <<: *default
  database: myapp_development

  # The specified database role being used to connect to postgres.
  # To create additional roles in postgres see `$ createuser --help`.
  # When left blank, postgres will use the default role. This is
  # the same name as the operating system user that initialized the database.
  username: myapp

  # The password associated with the postgres role (username).
  password: <%= ENV['MYAPP_DATABASE_PASSWORD'] %>

  # Connect on a TCP socket. Omitted by default since the client uses a
  # domain socket that doesn't need configuration. Windows does not have
  # domain sockets, so uncomment these lines.
  #host: 127.0.0.1
  host: 10.0.0.99

  # The TCP port the server listens on. Defaults to 5432.
  # If your server runs on a different port number, change accordingly.
  port: 5432
...

finally, you have to modify postgresql's pg_hba.conf file (located in postgresql's data folder) to give permission for the incoming network connection.

example:

...
# From rails myapp in local Ubuntu WSL distro
host    myapp_development myapp         10.0.0.99/32            md5
...

current documentation for WSL 2 says WSL 2 will also work using the ip address of the host. So this method should continue to work for WSL 2. docs: Accessing Windows Applications From Linux

@brandon-olin I have the same error. Did you manage to solve it?

I installed all with no problem, but when I go to open my site show me this error:
![https://prnt.sc/s2201n]
![https://prnt.sc/s220ev]
![https://prnt.sc/s220k5]

how to solve it?

I've tried this 5 times and they all fail in a different spot, first being the MySQL install, then the GitHub SSH Key, then 3 other random failures, any way to completely strip it from my system and start fresh?

i cant do rake db:create, everytime i get this error

Created database 'guardcenter_development'
could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

PG::ConnectionBad: could not connect to server: No such file or directory

I had the same issue. What I did is:

• Uninstall Postgresql
• Install it again by following the instructions here: https://docs.microsoft.com/en-us/windows/wsl/tutorials/wsl-database#install-postgresql
• open a terminal and run "psql -U postgres"
• create a new user by running "CREATE USER user_name WITH PASSWORD 'your_password';"
• check if the user is created "\du"
• add some roles "ALTER ROLE user_name CREATEROLE CREATEDB"
• update your database.yml file with your new user credentials.
• run "rake db:create"
• your DB should be created.

Anyone have any idea what went wrong?

your solution worked to me too

error: chmod on /mnt/c/code/myapp/.git/config.lock failed: Operation not permitted

If you want to use Postgres

Note that this will expect a postgres user with the same username

as your app, you may need to edit config/database.yml to match the

user you created earlier

SOLUTION:
close all shell windows
open a new windows powershell
wsl --shutdown
exit
Open ubuntu
rails new myapp -d postgresql

could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

Thanks. My app is working. I had to follow ROD's solution above plus install a newer version of yarn so that I could install webpacker.

sudo apt-get update
sudo apt-get install yarn
rails webpacker:install

You'll also want to add host/port/username/password to default in the database.yml before running rake

why is this ? : helloworld@DESKTOP-BT0GAQJ:/mnt/c/code$ rails new myapp -d postgresql

Thank you so much. I'm super excited to find out this Windows 10 discussion thread.

For anyone having problems with WSL and Postgres when running rake db:create, try adding host: 127.0.0.1 in config/database.yml to default: &default as you're using TCP, not a Unix socket.

Hi
after rake db:create I got and error
rake aborted!
LoadError: cannot load such file -- /mnt/c/myapp/config/application
/mnt/c/myapp/rakefile:4:in require_relative'
/mnt/c/myapp/rakefile:4:in'
(See full trace by running task with --trace)

thank you for this article!... I am new to rails but this article made it so much simple for me, thank you!

Small newbie error occurred for me. I got "git@github.com: Permission denied (publickey)." There were two problems. There was a prompt that had asked me for a name for the file for the generated key. I didn't know that this had to be a particular name, so I made up my own name. Also, the two files created were placed in the wrong folder. So I moved the files that I renamed to id_rsa.pub and id_rsa from my home directory to the folder /.ssh and then tried to connect again. This time I was successful.

Hello, I was following the instruction here. When I created a new app:

rails new myapp -d postgresql

It created the "myapp" application without the config directory. In addition, when I installed the dependencies for Ruby, these two commands:

libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev
libcurl4-openssl-dev software-properties-common libffi-dev

are not found (according to the terminal. All I did was "copy and paste" these commands, so there wasn't any potential typos there)

Because I later installed PostgreSQL, so hopefully, the command above for sqlite3 is not that necessary but the one for openSSL remains a concern.

Also, when I ran: rake db:create

rake aborted!
LoadError: cannot load such file -- /mnt/c/myapp/config/application
/mnt/c/myapp/rakefile:4:in require_relative'
/mnt/c/myapp/rakefile:4:in'

Someone on this board suggests that "application" be changed to "application.rb" in Rakefile, I tried that but it didn't help. Also, my application was created with the config directory missing :-)

Sorry for multiple problems. Any help will be much appreciated. Thanks!

Elijah, I appreciate your prompt assistance! I was able to run the above two commands ... However, when creating a new rails app:

rails new myapp -d postgresql

It seemed to have a file and directory permission issue that prevents the rest of the myapp directory from being created (please see below):

from ~/.rbenv/versions/3.0.2/lib/ruby/3.0.0/fileutils.rb:1346:in chmod': Operation not permitted @ apply2files - /mnt/c/code/myapp/bin (Errno::EPERM)

from ~/.rbenv/versions/3.0.2/lib/ruby/gems/3.0.0/gems/thor-1.1.0/lib/thor/actions/file_manipulation.rb:154:inchmod'
...

I did set: chmod 700 fileutils.rb
I even set: chmod 777 ruby (on the ruby directory) but neither helped.

Any idea ? Thanks!

I got it. My Ruby on Rails app is up and running now. Thanks again!

Hello again

I would like to be able to run rails commands from within the Visual Studio Code built-in terminal. They work fine on WSL terminals but I prefer to run them from within the VS code terminal. So when I ran something like "rails console" in VS Code, it said "The term 'rails' is not recognized as the name of a cmdlet, function, script file, or operable program ..." Upon some research on Google, someone suggests that the path to the rails/bin directory be added as an environmental variable. This is actually not hard. The hard part is to figure out where in the world rails was installed on WSL :-), can't find it. I know that my WSL was installed in C:\Users\tommy\AppData\Local\Packages but can't find the rails directory in Packages. Any idea ? Thanks again !

Elijah, you are the man (again) ! It worked, thanks a lot !

When running rake db:create

I get this error

How do i fix this?

Good article thanks... without it, I would be stuck for a week. I wasted 5 hours trying to get windows, ruby, rails and intellij IDEA to play together and gave up. I hit a few snags on this mostly at the end due to different ubunutu and ubuntu LTS (whatever that is) being installed and also there was some wierd issue with WSL not enabling systemctl by default, wtf? oh well, I have a working server so thanks. Wish they would make and keep up to date a good yum/rpm and windows installers, standup time is important for any software, but still re-learning ruby so...

anyone got it working? if yes, maybe post your conf, im on win 11, all good till rake db:create PG::ConnectionBad: could not connect to server: Connection refused
Is the server running on host "127.0.0.1" and accepting
TCP/IP connections on port 5432?
i modified the postgres conf to listen to wls ip, but im stuck here, reading a lot of copy paste articles, all sayin u need to start postgres service, but thats a nonsense if u use it in windows, anyway, im stuck here, any help is welcome.

I’ve got identical issue following from that guide on Win10 WSL.

And i found this issue may be solved with Chmod/Chown WSL Improvements
https://devblogs.microsoft.com/commandline/chmod-chown-wsl-improvements/ 32

Use
sudo umount /mnt/c sudo mount -t drvfs C: /mnt/c -o metadata
to change /mnt/c setting and it works for me

*You must delete files from incomplete rails new command first

    bin/rails db:create

    bin/rails db:create

Hi Zainab, first in file explorer go to C:/ and delete myapp folder.
Then open terminal or cmd what whever you use for WSL and paste this command:
sudo umount /mnt/c sudo mount -t drvfs C: /mnt/c -o metadata
After try again:
rails new myapp -d postgresql
It should work

Did the:
rails new myapp -d postgresql command worked?

thank you very much for your reply but this is what i have

open your editor (eg, Atom, Visual Code ... ) in the myapp app folder, go to config/database.yml find this lines

# The specified database role being used to connect to postgres.
# To create additional roles in postgres see $ createuser --help.
# When left blank, postgres will use the default role. This is

Warning: The database defined as "test" will be erased and

re-generated from your development database when you run "rake".

Do not set this db to the same as development or production.

test:
<<: *default
database: myapp_test

As with config/secrets.yml, you never want to store sensitive information,

like your database password, in your source code. If your source code is

ever seen by anyone, they now have access to your database.

Instead, provide the password as a unix environment variable when you boot

the app. Read http://guides.rubyonrails.org/configuring.html#configuring-a-database

for a full rundown on how to provide these environment variables in a

production deployment.

On Heroku and other platform providers, you may have a full connection URL

available as an environment variable. For example:

DATABASE_URL="postgres://myuser:mypass@localhost/somedatabase"

You can use this database configuration with:

production:

url: <%= ENV['DATABASE_URL'] %>

production:
<<: *default
database: myapp_production
username: myapp
password: <%= ENV['APMANAGER_DATABASE_PASSWORD'] %>

just add your password
