title: I can not get Moltin Laravel Cart to install
body: <p>I can not get Moltin Laravel Cart to install. It always tells me that <code>Your requirements could not be resolved to an installable set of packages</code>.</p>
  
  <p>Get this output from the Terminal:</p>
  
  <p><strong>Problem 1</strong></p>
  
  <ul>
  <li><p>Installation request for <code>moltin/laravel-cart dev-master</code> -> <code>satisfiable by moltin/laravel-cart[dev-master]</code>.</p></li>
  <li><p><code>moltin/laravel-cart dev-master</code> requires <code>moltin/cart dev-master</code> -> <code>no matching package found</code>.</p></li>
  </ul>
  
  <p><strong>Potential causes:</strong></p>
  
  <ul>
  <li>A typo in the package name</li>
  <li>The package is not available in a stable-enough version according to your minimum-stability setting</li>
  </ul>
  
  <p>I just have added the requirement in the composer.json file as the tutorial says</p>
  
  <pre><code>...
  "require": {
  "laravel/framework": "4.1.*",
  "intervention/image": "dev-master",
  "moltin/laravel-cart": "dev-master"
  },
  ...
  </code></pre>
  
  <p>Could anybody tell me how to fix it?</p>
