Laravel Gulp not creating js folder

I am currently trying to get gulp to run on my Laravel project.

I can successfully run gulp on my app.scss

I am trying to run gulp on a test coffee script, the coffee script is found in resources > assets > coffee > test.coffee

here is my gulpfile.js

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

/*

 | for your Laravel application. By default, we are compiling the Sass
 | file for our application, as well as publishing vendor resources.
 |
 */

elixir(function(mix) {
    mix.sass('app.scss');
    mix.coffee();
});

When I run gulp I get this error.

fetching Sass Source Files...
   - resources/assets/sass/app.scss


Saving To...
   - public/css/app.css
