title: compass not working with mithril yeoman generator
body: <p>I am trying to run the <a href="https://github.com/hung-phan/generator-mithril" rel="noreferrer">Mithril yeoman generator</a> unfortunately it falls over on <i>grunt serve</i> with the error</p>
  
  <p><b>Warning: Running "compass:server" (compass) task Warning: Couldn't find the compass binary. Make sure it's installed ...</b></p>
  
  <p>I can of course use --force to continue and it works fine but the css is not included which is a bit pointless, and my next option would be to modify the gruntfile to only use Sass without Compass.</p>
  
  <p>Note I have tried of the following suggestions from this <a href="https://github.com/gruntjs/grunt-contrib-compass/issues/66" rel="noreferrer">issue log for grunt-contrib-compass</a>:</p>
  
  <pre><code>npm install grunt-contrib-compass
  sudo gem install sass
  sudo gem install compass
  </code></pre>
  
  <p>Thanks</p>
