title: How to resolve "You need to have Ruby and Sass installed and in your PATH for this task to work" Warning?
body: <p>I am in the process of setting up a new Mac for work. I have installed Grunt &amp; Grunt CLI globally. Then I did a <code>npm install</code> inside a project folder to install all dependencies.  </p>
  
  <p>No problems so far, but as soon as I try to run the <code>sass:dist</code> task, I get this warning:  </p>
  
  <pre><code>Warning: You need to have Ruby and Sass installed and in your PATH for
  this task to work. More info:
  https://github.com/gruntjs/grunt-contrib-sass Use --force 
  to continue.
  </code></pre>
  
  <p>What I understand is that I need to have Ruby and Sass installed on a more global level for this task to run. As I am still pretty new to working with the terminal, I did a quick search to find out what <code>PATH</code> is - seems like its some system path (that can be changed) where important data is stored.  </p>
  
  <p>Does this mean I can simply do a <code>sudo grunt install contrib-sass -g</code> to resolve the issue? And what about Ruby – I always thought its already installed on OS X?</p>
