LoadError on line ["51"] when trying compass watch command

Question

I am new at SASS, but I have been trying to use the "compass watch config.rb" command but when I run it I get:

LoadError on line ["51"] of /usr/local/rvm/rubies/ruby-1.9.3-p392/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb: cannot load such file -- animation

Run with --trace to see the full backtrace

Any help that anyone could offer would be great.

I tried uninstalling and reinstalling the sass and compass gems.

Answer 1

I got it going now. Turns out that I needed to install the "animation" gemfile.

gem install animation --pre

Thanks for everyones help.
