title: No matching distribution found for PyQt5
body: <p>I install a rasbian os on my vmware workstation and I am currently trying to install some packages and modules. I have a problem with <strong>pip</strong>. I try:</p>
  
  <pre><code>sudo pip install PyQt5
  sudo pip3 install pyqt5
  sudo python3 -m pip install PyQt5
  </code></pre>
  
  <p>I got the same error.</p>
  
  <pre><code>ERROR: Could not find a version that satisfies the requirement pyqt5 (from versions: none)
  ERROR: No matching distribution found for pyqt5
  </code></pre>
  
  <p>I try to install PyQt5 manually and for that I install <code>sip</code> with <code>sudo pip3 install sip</code> after that  I try to configure pyqt5 files with <code>python configure.py</code> but I got this error:</p>
  
  <pre><code>Error: Unable to import PyQt5.sip. Make sure you have configured SIP to create a private copy of the sip module.
  </code></pre>
  
  <p>I already install sip. But my main problem is about pip. It's not working like I expect</p>
  
  <p>I'm not sure if it's about pip or it is a problem about operating system (or if it is about me). </p>
  
  <p><code>python --version</code><strong>:2.7.16</strong></p>
  
  <p><code>python3 --version</code><strong>:3.7.3</strong></p>
  
  <p><code>pip --version</code> I got the error</p>
  
  <pre><code>Traceback (most recent call last):
