I successfully installed Sass, but I'm having trouble importing Compass.

The following is the error detail:

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

I'm seeing this issue using Rails 4.0.2 and compass-rails 1.1.3

I got past this error by moving gem 'compass-rails' outside of the :assets group in my Gemfile

It looks something like this:

# stuff
gem 'compass-rails', '~> 1.1.3'
group :assets do
  # more stuff
end

If you're like me and came here looking for a way to make sass --watch work with compass, the answer is to use Compass' version of watch, simply:

compass watch

If you're on a Mac and don't yet have the gem installed, you might run into errors when you try to install the Compass gem, due to permission problems that arise on OSX versions later than 10.11. Install ruby with Homebrew to get around this. See this answer for how to do that.

Alternatively you could just use CodeKit, but if you're stubborn like me and want to use Sublime Text and command line, this is the route to go.

I was uninstalled compass 1.0.1 and install compass 0.12.7, this fix problem for me

$ sudo gem uninstall compass
$ sudo gem install compass -v 0.12.7

In short, if you've installed the gem the run:

compass compile

in your rails root dir
