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 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}

Answer 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
   

Answer 3

I had the same problem and then I realised that I had two compass versions, so by doing:

compass watch or compass compile

The compiler didn't know which compass version it should use to compile. So, what you can do is explicitly indicate the compass version to work with:

compass _1.0.3_ watch

There's another interesting thread.

Answer 4

In case you are using Ubuntu it may be a problem with apt-get and rvm colliding.

Try removing rvm with rvm implode and then run

sudo apt-get install ruby-compass 

compass watch worked for me after that.

Answer 5

I believe this is due to versioning conflicts with sass.

https://rubygems.org/gems/compass gem is currently at v0.12.16 currently - add this to Gemfile

gem 'sass', '3.2.19'
gem 'compass', '0.12.6'

You may be required to uninstall all versions of both gems first.
