\ Here's my experience with Ruby on Rails **

I'm getting the following when I select Project -> Run:

14:46:13 web.1  | 'bundle exec rackup config.ru -p $PORT' started with pid 274

I've executed 'rvm use ruby' in the Terminal, but I still get the same error.

I've also tried 'bundle exec rackup config.ru -p 5000' in the Terminal, then I get gem errors. 'bundle install' helped with some gems, but compiling the postgres gem failed.

I ran 'sudo apt-get install -y postgresql', that worked.

'bundle install' still failing:

'sudo bundle install' doesn't work:

codebox@7c726cec32e4:~/workspace$ sudo bundle install

I'd be happy to RTFM, but there doesn't seem to be any content under the "Autorun" topic: http://help.codebox.io/ide/autorun.html

@terryg Sorry about that. There's a fault in the default permissions set for rvm, we were planning on pushing new stacks in the coming days, so I'll bundle a fix for this in the ruby stack.

In the meanwhile, run this command once and you should be good : 

sudo chmod o+rw -R /usr/local/rvm/

This fixes the permission issues with rvm.

After than I can run sinatra with no issues, using this sample code :

require 'sinatra'

get '/' do
  'Hello world!'
end

set :bind, '0.0.0.0'

Make sure that your server binds to 0.0.0.0 so it can be accessed externally.

@terryg Let me know if this helps.

Thanks for reporting this and sorry for the inconvenience.

Thanks @AaronO! Did you run this via Project -> Run or directly in the Terminal? Can you share the Procfile? I'm still getting the "rvm use ruby" first error.

@AaronO thanks for posting the solution, I got my gems installed and my rails app working
