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

Answer 1

This specific version works well on both:

gem 'sass', '3.3.0.alpha.149'
gem 'compass', '0.12.2'

They might not be compatible with each other that's why you're getting those errors (considering you're using a bleeding edge version).

Answer 2

I was able to fix it by doing this

gem uninstall sass
gem install sass -v 3.2.12

This is definitely due to a version dependency issue, you are better off fixing your grunt task to make it forward compatible with the newer versions of saas, compass and so on.

Answer 3

The following combinations worked for me:

gem install compass --pre
gem install sass -v 3.3.3

Answer 4

I had to setup a gemfile with the correct versions (this error is caused by mismatched SASS and Compass versions, for me). I used thew following with bundle install to fix the problem:

source "https://rubygems.org"

gem 'bootstrap-sass', "~> 3.2.0"
gem 'sass', [ "< 3.5" , ">= 3.3.13" ]
gem 'compass', "~> 1.0.1"
gem 'compass-core', "~> 1.0.1"
gem 'compass-import-once', "~> 1.0.5"
gem 'chunky_png', "~> 1.2"
gem 'rb-fsevent', ">= 0.9.3"
gem 'rb-inotify', ">= 0.9"

Answer 5

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.

Answer 6

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.
