Custom importers not loaded/ working

[gucki]

I created a custom sass importer in my rails initializers (so its defined for sure) like

module Sass
  module Importers
    class Sprite < Base
      ...
    end
  end
end

which should basically be used for all @import "sprite:xxx" imports. However it's never called, as I get

Sass::SyntaxError: File to import not found or unreadable: sprite:icons.
Load path: Sass::Rails::Importer(.../application.scss)

You need to add your importer to the sass load path:

config.sass.load_paths << Sass::Importers::Sprite.new
