title: How to install nodejs 4.1.2 with HomeBrew
body: <p>I installed NodeJs with the following commands: </p>
  
  <pre><code>brew install node
  </code></pre>
  
  <p>It downloaded the version 5.5.0 of NodeJs. </p>
  
  <p>I want the version <strong>4.1.2</strong> (for Ionic compatibility). </p>
  
  <p>How to download this specific one? </p>
  
  <p>I can't run <code>brew switch node 4.1.2</code> since I've never downloaded it before. </p>
