Laravel 4 - Assets Pipeline not compiling?

So you have installed this package: https://github.com/CodeSleeve/asset-pipeline

But something isn't quite right... Why is this thing not compiling?

Most likely the problem is your Laravel Environment Configuration:

Open:

bootstrap/start.php

Change this dummy string to your actual machine name:

'local' => array('your-machine-name')

To find out your machine name just type this in your Terminal:

hostname 

You may also want to clear your cache then run:

php artisan assets:clean
