title: Reportlab install: need Pillow. Pillow install: need zlib. Zlib install: file not found
body: <p>Relevant details:</p>
  
  <ul>
  <li>Windows 8</li>
  <li>Python 2.7 and 3.7 installed. I'm trying to migrate from 2.7 to 3.7, starting by making sure I have every package I use installed for 3.7</li>
  <li>IDE is PyCharm. I tried installing packages that way, but proxy blah blah connection issues blah blah, gave up on that rabbit hole</li>
  <li>I am installing from CMD, where I also have a proxy issue, so I'm downloading packages and installing from there.</li>
  <li><p>pip version 19.0.3 </p>
  
  <pre><code>C:\Users\me\Downloads&gt;py -3 -m pip install zlib-1.2.11.tar.gz
  Processing c:\users\me\downloads\zlib-1.2.11.tar.gz

  </ul>
  
  <p>I have tried installing zlib1211 as well. 
  I have tried 17 versions of Pillow. 4.0.0, 3.4.2 (succeeded but Reportlab requires 4.0 minimum), 6.1.0, and I've tried .whls and .eggs and such to no avail. I've been to dozens of pages looking to solve each issue I've come across, and I have no more things to try. zlib isn't even in pypi. </p>
  
  <p>What else can I do? </p>
