Why does "compass watch" say it cannot load sass/script/node (LoadError)?

Question

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 rvm to update Ruby. I checked my custom_require.rb file but I really don't know what to look for. It seems to be trying to load the file "sass/script/node" somewhere and from http://sass-lang.com/docs/yardoc/Sass/Script/Node.html I gather the filepath - but I have nothing there.

Anyone have any ideas?

Uninstall sass and reinstall it with the following:

gem uninstall sass
gem install sass

There was an issue with my installation of sass and doing this fixed the issue.
