Grunt task Compass fails - Could not find RubyGem compass (>= 0)

Question

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:

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 (>= 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

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.

When I run $ gem list I get the following:

*** LOCAL GEMS ***

bigdecimal (1.2.0)
bundler (1.5.1)
bundler-unload (1.0.2)
executable-hooks (1.2.6)
gem-wrappers (1.2.4, 1.2.1)
io-console (0.4.2)

rake (0.9.6)
rdoc (4.0.0)
rubygems-bundler (1.4.2)
rvm (1.11.3.8)
test-unit (2.0.0.0)

I then tried running $ sudo gem update --system but I got hte following response: Latest version currently installed. Aborting.

Any ideas, anyone?

Answer 1

Looks like SASS and Compass gems are missing, try installing SASS & Compass

sudo gem install sass

sudo gem install compass

For windows use following commands

gem install sass

gem install compass

Hope this works :)

Answer 2

this is what I had to do. I uninstalled and reinstalled sass and compass then run: bundle update i18n

Everything seemed to work after that!
