Rails 3 Compass import problem - "File to import not found or unreadable"

[Eric Wright]

I have a Rails 3 app with compass installed, with two simple scss
files:

common.scss:
$body-background: blue;

main.scss:
@import 'common';
//@import 'compass';

body {
background: $body-background;
}


If I comment out the "@import 'compass';" line, this all works -- I
get a blue background, so I know Sass is working. But if I uncomment
that line I get the error:

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 thought maybe it doesn't know how to find compass, so I added the
following to config/compass.rb:

add_import_path "/Library/Ruby/Gems/1.8/gems/"

But that didn't make any difference. I've googled for two days with
no luck. Why can't Sass import anything from compass?

-----

For reference, here is the entire 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/"

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"



(Let me know if you need any other info to help.)

Did you add compass to your Gemfile? This is what happens when compass isn't loaded.

Yes, compass is in the Gem file. The line verbatim is

gem "compass", ">= 0.11.1"

And when I run $bundle install, I get

$ bundle install
Using compass (0.11.1)
... other gems ...
Your bundle is complete! Use `bundle show [gemname]` to see where a
bundled gem is installed.
$ bundle show compass
/Library/Ruby/Gems/1.8/gems/compass-0.11.1
$

I feel like Sass doesn't know where to find the compass files. I
don't know enough about the internals of Sass or Compass to know where
this is set. In my head it's something like (in pseudocode),
Sass.add_load_path(Compass.path_to_gem)

I'd appreciate any troubleshooting tips -- ways to crack open what's
happening and figure out which part of the app is dropping the ball.

What version of rails?

[Eric Wright]

$ rails --version
Rails 3.0.7
$

I think it's best if we can chat interactively. Can you come to #compass on irc.freenode.net?

When would be a good time for you? I'm away until Sunday evening or we could talk any evening during the week. 

(and thanks for the help - I really appreciate it)

Okay, after help from Chris we were able to find the offending line.
In config/environments.rb I had this line:

Sass::Plugin.options[:template_location] = {
"#{RAILS_ROOT}/app/stylesheets" => "#{RAILS_ROOT}/public/stylesheets"
}

With the currently versions of Rails (I have 3.0.7) and Compass
(0.11.1) this line is NOT NECESSARY. I added it after following a
tutorial. If sass can't find compass, it might be because this line is
messing up your Sass::Plugin.options[:template_location].
