Sass import error in Rails 3 app - "File to import not found or unreadable: compass"

Question

I have a Rails 3 app on which I successfully ran compass init rails ./ --using blueprint. I can @import files from the /stylesheets directory, but I get an error when I try to @import compass.

Right now the app has two simple sass files:

common.scss

$body-background: blue;

main.scss

@import "common";
//@import "compass";

body { 
  background: $body-background; 
}

With the @import "compass" line commented out, this works -- I get a blue background, so I know Sass is working.

If I uncomment the line, and try to import compass or blueprint or anything else, I get an error like this.

Syntax error: File to import not found or unreadable: compass.
              Load paths:

                /Users/eric/path/to/myrailsapp/app/stylesheets
        on line 2 of /Users/eric/path/to/myrailsapp/app/stylesheets/main.scss

1: @import "common";
2: @import "compass";
3: 
4: body { 
5:  background: $body-background; 
6: }

I had through maybe I had to explicitly tell Sass where to find the Compass gem, so I added an add_import_path line to config/compass.rb:

require 'compass'
require 'html5-boilerplate'

project_type = :rails
project_path = RAILS_ROOT if defined?(RAILS_ROOT)
add_import_path "/Library/Ruby/Gems/1.8/gems/"  # unfortunately this has no effect

http_path = "/"
css_dir = "public/stylesheets"
sass_dir = "app/stylesheets"
images_dir = "public/images"
javascripts_dir = "public/javascripts"
cache_dir = "tmp/sass-cache"

http_images_path = "/images"
http_stylesheets_path = "/stylesheets"
http_javascripts_path = "/javascripts"

I have been googling for two days, and can't determine why I'm having this problem with basic @import statements. How do I tell Sass where to find the Compass and Blueprint libraries?

Answer 1

I was getting this error.

I changed this line in my application.rb from:

Bundler.require(:default, Rails.env) if defined?(Bundler)

to:

Bundler.require(*Rails.groups(:assets => %w(development test))) if defined?(Bundler)

Also, make sure the files are names something.css.sass NOT something.sass

And one other thing, I had an old compass.rb file in my config directory which isn't needed in Rails 3.2. Deleting that also solved this problem for me.
