Ruby On Rails, Error running command “rails generate controller”, Input/output error @ rb_sysopen, (Errno::EIO)

Question

In the beginning, when I run rails generate controller welcome homepage into my project's dir, the command works OK and produces the app/controllers/welcome_controller.rb and route get welcome/homepage

User1@My-Machine:~/MyProject$ rails generate controller welcome homepage
/home/User1/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/railties-4.2.6/lib/rails/app_rails_loader.rb:39: warning: Insecure world writable dir /home/User1/.rbenv/versions in PATH, mode 040777
      create  app/controllers/welcome_controller.rb
       route  get 'welcome/homepage'

immediately after that, the command runs into the following error:

/home/User1/.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/User1/MyProject/config/routes.rb (Errno::EIO)

followed by a list of files.

Does anyone know how this can be resolved?

Answer 1

This answer is a bit of a copout, but my experience with the current versions of WSL is that rbenv has issues running in WSL, wheras RVM seems to work okay. The original question sounds like you may be moving linux specific files like /home/user/file (from the appdata area) from the Windows interface -- definitely don't do that. Only manipulate those files from bash, as corruption and oddities will occur .

Not sure why things aren't being created or seen correctly in your setup, but in general, here's what has worked for me:

Using RVM, and with the help of this guy I came to the conclusion that I need to

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

and use

bash --login

to log into the interactive version of bash from Windows.

I've been successfully creating and working with projects from both Bash and Windows in the mounted space, ie /mnt/c/Users/Tim/Desktop/railsapp

I run generators and whatnot from bash, but edit the content of the files from Sublime in Windows.

Good luck!
