title: Can't seem to use the SASS --watch command when installing
body: <p>Just node installed sass and keep getting an error when using: </p>
  
  <p><code>node-sass style.scss --watch</code></p>
  
  <p>This seems like a fairly recent bug since no one on the web has answered it.</p>
  
  <p>Heres the error:</p>
