title: rails -v cannot load such file -- rails/cli (LoadError)
body: <p>Ubuntu 14.04.</p>
  
  <p>So everything was working fine and I had my terminal open with two tabs - one tab had webbrick running on my sebcoles project, and the other tab I used to clone my english_teacher repo. It all downloaded fine and I changed into the directory.</p>
  
  <p>I'll just paste everything here - it's all pretty clear:</p>
  
  <pre><code>andrew:projects$ cd pinteresting
  RVM used your Gemfile for selecting Ruby, it is all fine - Heroku does that too,
  you can ignore these warnings with 'rvm rvmrc warning ignore /home/andrew/projects/pinteresting/Gemfile'.
  To ignore the warning for all files run 'rvm rvmrc warning ignore allGemfiles'.
  
  ruby-2.1.5 is not installed.
  To install do: 'rvm install ruby-2.1.5'
  
  andrew:pinteresting$ rvm install ruby-2.1.5
  
  Warning, new version of rvm available '1.26.11', you are using older version '1.26.10'.

  Searching for binary rubies, this might take some time.
