title: Grunt task Compass fails - Could not find RubyGem compass (>= 0)
body: <p>I recently transfered machines from an iMac to a new Mac Book Pro with Mavericks. All was well but I noticed that Grunt was crashing when I saved a file (the auto update wasn't working). I tried to update my system but when I run my grunt tasks via the terminal I get the following error:</p>
  
  <pre><code>Running "compass:dev" (compass) task
  /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:777:in `report_activate_error': Could not find RubyGem compass (&gt;= 0) (Gem::LoadError)
      from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:211:in `activate'
      from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:1056:in `gem'
      from /usr/bin/compass:18
  </code></pre>
  
  <p>Would anyone have any advice on how to fix this? I have removed compass from my project and done an npm install, nothing has changed. </p>
  
  <p>When I run <code>$ gem list</code> I get the following:</p>
  
  <pre><code>*** LOCAL GEMS ***
  
  bigdecimal (1.2.0)

  </code></pre>
  
  <p>I then tried running <code>$ sudo gem update --system</code> but I got hte following response: <code>Latest version currently installed. Aborting.</code> </p>
  
  <p>Any ideas, anyone?</p>
