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"?
Couldn't create 'GuardCenter_test' database. Please check your configuration.
rake aborted!
PG::ConnectionBad: 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"?

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.

Hi,

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!
