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

Solution 1:

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.

Solution 2:

In my case, Sass version was not compatible with Compass.

FIX :

1. uninstall Sass AND Compass

   gem uninstall compass
   gem uninstall sass
   

2. install Compass who will install a compatible Sass engine automaticaly

   gem install compass
   

Solution 3:

This combination is finally working for me to bring Compass and SASS Sourcemaps together:

Gemfile

gem 'sass', '3.3.0.alpha.149'
gem 'compass', '0.12.2'
gem 'compass-sourcemaps', "~> 0.12.2.sourcemaps.57a186c"

Compass config.rb

sass_options = {:sourcemap => true}

Solution 4:

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).
