title: Rails: SASS not creating the CSS files
body: <p>SASS is not creating the CSS files, but HAML is working just fine.</p>
  
  <p>I ran the following command:</p>
  
  <pre><code>$: sass --watch scss:stylesheets
  [true, ["scss", "stylesheets"]]
  </code></pre>
  
  <p>My <strong>main.scss</strong> file contains the following:</p>
  
  <pre><code>/* main.scss */
  
  body {
      background: #000000;
  }
  </code></pre>
  
  <p>The main.css file never gets generated. So I ran the following:</p>
  
  <pre><code>$: sass --update
  NoMethodError: undefined method `split' for nil:NilClass
    Use --trace for backtrace.
  </code></pre>
  
  <p>What gives?</p>
  
  <ul>
  <li>Running Rails 3</li>
  <li>I've tried both <strong>haml</strong> and <strong>haml-edge</strong></li>
  </ul>
