How to make use of compass in laravel?

With laravel-elixir-compass (and gulpfile.js from README.md) it says:

$ gulp
module.js:340
    throw err;
    ^

Error: Cannot find module 'laravel-elixir/ingredients/helpers/utilities'
    at Function.Module._resolveFilename (module.js:338:15)
    at Function.Module._load (module.js:289:25)
    at Module.require (module.js:366:17)
    at require (module.js:385:17)
    at Object.<anonymous> (/srv/http/sl/node_modules/laravel-elixir-compass/index.js:4:17)
    at Module._compile (module.js:425:26)
    at Object.Module._extensions..js (module.js:432:10)
    at Module.load (module.js:356:32)
    at Function.Module._load (module.js:313:12)
    at Module.require (module.js:366:17)
    at require (module.js:385:17)

So, I concluded it relies on elixir <= 0.9.1, since this is when the file was renamed. And this is the closest commit with bumped version I could find.

Then I noticed "Project has moved" warning in README.md.

With laravel-elixir-sass-compass (and gulpfile.js from README.md):

With any path passed (mix.compass('app.sass')):

$ gulp

Solution

As it appears, it just can't find any files to be compiled. So, the basic version of gulpfile.js is to be like so:

var elixir = require('laravel-elixir'),
    path = require('path');

require('laravel-elixir-sass-compass');

elixir(function(mix) {
    mix.compass('*', 'public/css', {
        sass: 'resources/assets/sass'
    });
});

Here's the relevant issue.
