title: Trouble installing sip on osx for python3
body: <p>I'm trying to install sip so I can install PyQt5. When I try to install with pip it gives the following error.</p>
  
  <pre><code>&gt;&gt;&gt;pip3 install sip
  Collecting sip
    Could not find a version that satisfies the requirement sip (from versions: )
  No matching distribution found for sip
  </code></pre>
  
  <p>Does anyone know how I can get pip to find the sip package? I've also tried installing with brew but I need to install version 4.19 and brew installs 4.18.</p>
