Fallback

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?


Fallback

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!


Fallback

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

The main issue here is that inotify has been completely broken in WSL. So even if you disable listeners, tools like Guard won't work. Insiders are soon getting a partial fix, whereby files changed within WSL itself can be watched without errors.

Here's the test. First install inotify-tools, which give you some command line programs to monitor files:

$ sudo apt-get install inotify-tools

Then attempt to watch any file from the command line:

$ touch testfile.txt && inotifywatch testfile.txt
Establishing watches...
Failed to watch ./testfile.txt: Invalid argument

Note that's the same error that rb-inotify reports above.

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?

Hi, friend! You can install postgres in windows. To connect the app you only need a port of the database (I had the same issue at the beginin).

I'm getting the same error and can't figure out how to get around it. I've tried uninstalling and reinstalling Postgresql to no avail. Any thoughts?

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.

RIght click on the Ubuntu icon, go to properties and check the boxes under Edit Options and text selection

I would just suggest taking a look at http://cmder.net/ -- This tool is a terminal lifesaver for me on Windows. It is highly configurable. By default, it adds git and some linux tools to cmd, the default shell it uses, but also allows you to use any shell (MING64, Git Bash, PowerShell, the new Bash/Ubuntu for Windows).

Today I tried getting on with the default Bash for Windows which uses the older cmd terminal, but I went bananas. Cmder gives you the text tools you need!

J. Pablo Fernández

You probably need to reselect the ruby with rbenv or rvm.


Fallback

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!

Fallback

I was having this same issue and abandoned my attempt. If someone understands what's at hand here, that would be great.

Fallback

Not entirely sure on that one. Have you guys tried using rbenv instead?

Fallback

For me, that was with several attempts on different machines using my preferred rbenv -- I'm going to try RVM and report back.

Fallback

Curious to hear what you find out. I didn't have any issues personally, but only tested rbenv. Now my Windows 10 install is borked and I haven't had time to fix it so it boots again.

Fallback

Well, I've tossed and reinstalled WSL from scratch, and tried the RVM install instead. I found that I needed to do `bash --login` to reference my profile (and load rvm) if I left the terminal -- so it might be a good idea to reference that -- apparently the default session is not interactive.

Anyway -- I did not encounter the sticky directory issues while using RVM, but I am still having the same issue as above running generators. I've tried both `rails g scaffold hotdogs good tasty` and `bundle exec rails g scaffold hotdogs good tasty` to no avail.

I just wanted to add that using the RVM install, knowing to use `bash --login` when I hop in, and ignoring the usage of any commands that utilize spring (generators, console, rake test :( ), seems to be working relatively fluidly (including the majority of rake tasks).

Obviously those are some big issues, but at least I can clone my working project down and run it currently. My last few attempts with RailsInstaller have been horribly unproductive.

Fallback

Makes sense with the login shell. I wonder why they changed that, because I don't think that was how it used to be. Going to frustrate a lot of people if they keep that as the default.

Fallback

Got it!

This guy has a solution https://github.com/Microsof...

```
bundle config --delete bin
rake rails:update:bin
git add bin
```

I've successfully tested it using WSL/Bash on Win10, with the instructions posted above using the RVM install, after running `bash --login` to ensure interactive shell.

Fallback

I've tried numerous times using both the rvm and rbenv route and end up with the exact same issue as described above every time. I've reset the entire linux subsystem between each attempt.

Fallback

Seems they've been making some changes to it, one of those being it's not a login shell, so you'll have to do "bash --login" for now. Still other outstanding issues. Maybe they'll get some of them fixed soon.

Fallback

I posted this in the long chain of comments that follows this thread, I thought I'd add it back up here for you and future folks too.

Good to hear! This has to be frustrating.

I had the same problem and followed the fix above. The "rails generate controller welcome homepage" finally worked only to create the "app/controllers/welcome_controller.rb" and the route "get 'welcome/homepage'. Then produces the following error "/home/Username/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/thor-0.19.1/lib/thor/actions/inject_into_file.rb:98:in `binread': Input/output error @ rb_sysopen - /home/Username/MyProject/config/routes.rb (Errno::EIO)" and following several .rbenv file names with error lines. Any ideas?

Fallback

I saw your post on SO http://stackoverflow.com/qu... but don't have enough rep to comment there, so I'll comment here.

You mention not seeing routes.rb in bash, but seeing the file in Windows, and then proceeding to copy stuff around.

The file path you mention your project to be in is a straight up linux folder (/home/User1/stuff) as opposed to a shared, mounted directory in the Windows system. With this said, I've read that interacting with files on that side (burried in appdata or wherever) of the system from Windows causes problems because of the differences in how files are handled between the systems. So, as you mention in SO, trying to copy those files from Windows will likely lead to difficulties.

I've had success with my projects living in the Windows mount area -- for example:

```
cd /mnt/C/Users/Tim/Desktop
rails new hello_world
etc
```

With the files living there, it is easy to manipulate with Windows or Linux then without causing corruption (the worst of it seems to be line ending issues, which any proper text editor can deal with).

In addition, I was using rvm, instead of rbenv.

Without knowing too much more, I'd give generic recommendations akin to "reboot it and see what happens":

- run rbenv rehash
- run bundle install
- run chmod +t -R ~/.bundle
- consider running chown -R user:user /home/user
- cd /mnt/c/Users/User/Desktop && rails new hotdogs && cd hotdogs --- and try creating a controller from there -- pay attention to what happens to the actual output

Hope you find something -- I went through a bit of hell when I tried updating ruby recently, before WSL. I had a perfectly running Ruby 2.2.0 on my system with Rails -- tried upgrading, and went through 3 weeks of frustration in trying to get a working ruby again. The method I posted above has been working really great for me finally, but I don't dare mess with it again -- it's so damned fragile!

Fallback

Thank very much you for the recommendations. I created a new bash user to install rvm there and follow your recommendations (do you think is OK or I should reinstall the whole subsystem and use rvm this time?). I'll let you know whether it is worked for me too.

Fallback

Well, finally, the RVM installation with the fix above works fine, like you said! (I found no way to make rbenv installation operational). Thanks a lot!

Fallback

Hey @excid3:disqus -- You might want to consider noting some of this stuff in the Windows specific guide, unless you are in fact seeing people successfully using rbenv. Right now the guide says rbenv is the recommended way, but I haven't been able to get it to work on WSL without issues. If you know how, that information would also be appreciated :)

Fallback

I used rbenv just fine when I initially set things up. My Windows 10 install got corrupted so I need to reinstall it and try this again sometime to see how things have changed.


Fallback

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

I love you <3

Fallback

I agree with Anthony on this. I have the best of both worlds (solid windows gaming on a ridiculously fast machine and still have an ubuntu bash shell).

This is really perfect Chris. You're awesome.


Fallback

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!

It definitely can take a while sometimes. Depends on how powerful your computer is and stuff.The good news is you rarely need to do it so once it's done, you will be set for quite a while!

Fallback

why hours and not minutes?, does not seem like the download was much.

Fallback

Because compiling Ruby takes a lot of CPU power.

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?

Fallback

Hey Dale, you'll probably need to create that file if your Rails app doesn't have one. Some details on that file: http://edgeguides.rubyonrai...

I setup a new app and now I get the following message. I know something isn't configured correctly, but I don't know how to determine what it is.

Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

Fallback

After many times removing everything and starting over I finally resolved the issue. Or should I say this article fixed the problem. http://superuser.com/questi.... I was missing the /var/run/mysqld/mysqld.sock file. It is fixed and I am finally up and running with Rails on Bash on Ubuntu on Windows 10!

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

Fallback

Did you configure anything after the postgresql installation? I tried to follow the instruction here: https://github.com/Microsof... but it didn't work for me. Do you have any tips/comments that could help? Thanks

Fallback

BTW.. I did a standard postgresql install on windows and didn't do anything special in the linux side.. my rails app in rails can talk to the postgresql server running in windows.. localhost points to the same place linux and windows..

Fallback

Thanks for letting me know! I'll go and try this again in the future. Maybe I just messed something up

Fallback

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


Fallback

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!


Fallback

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?


Fallback

@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

Fallback

hey .. did all the things till the final step /
i had some problem so closed the bash screen and turned on again
now when i type ruby -v .. its says it to install same goes for rails everything

so .. far i dnwld everythng is gone ah ???

i dont understand help me

it took nearly 4 hrs fr me to reach final step

Fallback

It's likely that everything is installed but your terminal didn't automatically load rbenv again. Double check and make sure that you followed all the rbenv lines correctly to echo the lines into your .bashrc file.

Fallback

i used RVM to install

is that a problem ????

Fallback

I had the same problem.... this worked for me:
/bin/bash --login

after that I could use ruby -v, rails -v, even rails server
hope it helps :)
BTW I also used rvm

Fallback

So, today I found something better.... Open up the launcher of the bash and go to the properties.... change the target to "C:\Windows\System32\bash.exe ~ -c "/bin/bash --login"... after this you do not have to use the solution from previous comment every time you launch it.... This works automatically... It's based on the fact that normally you launch a non-login session, however, with these settings you, on the other hand, run a login session..... If you want to know more, read these threads http://askubuntu.com/questi... and https://github.com/Microsof...

Fallback

Hopefully that default changes in Windows as that's unexpected behavior from anyone who is used to opening bash with a login shell automatically on any Linux install.

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

Rails dev environment is not native on Windows, which is why you have to go through all the hassle.


Fallback

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.

Fallback

Nope, wrote it myself, but things are constantly changing with Bash on Windows so these instructions break often.

Fallback

The horror. I might as well Virtualbox the Rails environment and just work from there instead then. Thanks anyways.

Go for it. Like it says at the top of the post, this is for documenting it for Bash on Windows, not other approaches like VirtualBox.

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"

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 :)

Fallback

What version of postgres did you install on windows?

Fallback

pgsql - 9.6 and rvm 2.4.
Initially I installed pgsql on ubuntu bash, but it didn't work, some error(don't remember it), then i read somewhere that we need to install on windows, so installed on windows and in db.yml added host as localhost.

Fallback

Doesn't work with rbenv unfortunately. The pg gem won't install: fatal error: libpq-fe.h: No such file. If I run sudo apt-get install libpq-dev it can no longer find the gem file for some reason.

Fallback

Actually got it working! Woohoo...


Fallback

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.

Fallback

so go for rbenv?

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).

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.

Not sure if you ever got it working, and I don't have a solution really, but here are some thing's I would check.

Make sure the MySQL server is actually running. If so:

Get a visual MySQL Editor, there's alot of them, make sure your database encoding is UTF8, if it's not change it. The Visual Editor just makes it easier to check thing's out. It's a bit more simple than throwing commands into a console.

Check your Firewall, and make sure it's allowing connections on the MySQL servers port/s.

Make sure you have the correct permissions/privileges, both file system permissions, and privileges to access the MySQL service. For example MySQL may have been installed with only root, or admin access allowed. try opening the bash terminal as administrator, if that doesn't work try using sudo prefixed before commands (with, and then without admin privileges on the bash process.)

Sorry I couldn't give you a concrete solution, hope you get it working.

gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB

...and I never get a message convincing me that the keys are in place. I get something to the effect...

gpg: directory '/root/.gnupg' created
gpg: new configuration file '/root/.gnupg/gpg.conf' created
gpg: WARNING: options in '/root/.gnupg/gpg.conf' are not yet active during this run

Those last 3 lines always worry me. I get this same type of message whether I'm running the command in Windows 10 Bash on Ubuntu on Windows or when I run it in an Oracle virtualbox running the latest Ubuntu version. I've been having this issue for years now. I found another post that suggested I run this instead...

command curl -ssl https://rvm.io/mpapis.asc | gpg --import

...and that seems to get me what I need for the install and Rails to work. I just can't believe that I haven't seen anyone post about this error yet and that it's only happening to me....no matter what machine I'm on. Why doesn't this command work for me? gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB I've run this command on a few dozen virtualbox machines now and it's never worked without error messages at the end. When I ran this on my windows box and I still got the message, I figured I should finally post something. I've been getting a similar message since I started following these instructions since late 2015.

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.

Do I have to be in the Windows Insider Program to download Linux on my Windows 10 PC?

I had a problem when tried to run rake db:create after Postgress installed in Windows. It couldn't connect.
Here's the solution I've found here:

when you do not specify a hostname, postgresql clients (psql, pg_dump) will try to connect via a Unix socket, not TCP. Connection from Bash on Windows to Postgresql running on Windows must be via TCP (the error message mentioned that it could not connect on a Unix domain socket, but it hadn't clicked in my head). To force your connection to use TCP you must specify a hostname. The host can be specified with a command line flag -h localhost, via PGHOST environment variable, or via .psqlrc file. I added export PGHOST=localhost to the bottom of my ~/.bashrc file.
The second issue I had was that I expected psql to be able to connect to the local host without specifying a password, just as I do when running on Mac OSX. This was fixed by changing the Windows Postgres server's pg_hba.conf file. The default line in my installation for 127.0.0.1 was configured for md5 connection method. I changed it to trust, to match the configuration on my OSX installation. That makes the pg server trust any connection that can be made.

I also had to add a user in Postgres with the same name as it was in my Ubuntu Bash.
