sass compile error - StalenessChecker::Mutex (NameError)
This same issue started popping up for me today. I suppose there is something wrong with sass-3.2.11 or some configuration that I am not aware of.
To get past the issue for now I uninstalled the new version and installed an older version like so:
Uninstall sass
gem uninstall sass
Install version 3.2.10
gem install sass --version 3.2.10
Reinstall compass
gem install compass
This has been fixed in sass 3.2.12.
So all you need to do is update your sass gem
gem install sass
Should pull the latest version 3.2.12 or greater
i previously had updated the default OSX version with:
gem update --system
This created the problem - not a good idea to do on the 'out of the box' OSX version.
