I\'m having a problem with my compass watch command - it worked fine up until a few days ago. I have made no changes to my config files.
I reinstalled Compass, used
A variation on the above answers: for me (using Bootstrap for Sass), it turned out to be
gem install bootstrap-sass
that was needed in order to fix this problem. For me, the LoadError problem with Compass started after I updated the version of Ruby I was using.
