I was requiring sass-globbing in my extension, used in on a directory that had no files within it caused the error. commenting this out seems to of allowed the watcher to work
I'm getting the following error reported to me when trying to use the following command:
sass --compass --watch sass:css --sourcemap
ArgumentError: wrong number of arguments (4 for 3)
This is being pulled in to the config.rb require 'compass/import-once/activate' - Removing this, allows me to watch the files
