One Pixel Solid

On the subject of Sass, I noticed a pesky warning when running the sass watch command.

Warning: Unable to load CarbonCore. FSEvents will be unavailable.

Turns out if you’re getting this error it means your Terminal is actively polling a sass directory for changes rather than natively listening for changes. The former method being resource intensive. Not cool.

My attempts at getting rid of this error lead me on a labyrinth of ‘Stack Overflow’ suggestions which included installing RubyCocoa, which I found out wasn’t compatible with Ruby 1.9.2, but which then also failed to compile with Ruby 1.8.7 despite clear examples it should work! etc etc.

In the end the solution was simple.

gem install rb-fsevent
gem install fssm
