title: cannot run spyder (requires pyQT5 5.5+)
body: <p>I'm trying to run spyder, but I get the following message:</p>
  
  <pre><code>RuntimeError: Please check Spyder installation requirements:
  PyQt5 5.5+ is required (found v5.3.2).
  </code></pre>
  
  <p>I'm new to python, and I've been installing package with both pip and pip3. I don't know if this has created some kinds of conflict, but I don't seem to be able to update PyQt5 past version 5.3.2.</p>
  
  <p>Does anyone know how to resolve this? I thought I had the most recent version of PyQt5. I installed it literally minutes before trying to run spyder.</p>
