title: Cannot install pyqt5-tools - 'Could not find a version that satisfies the requirement pyqt5-tools'
body: <p>I try to install pyqt5-tools like this:</p>
  
  <pre><code>pip install pyqt5-tools
  </code></pre>
  
  <p>and the resulting out put is:</p>
  
  <pre><code>ERROR: Could not find a version that satisfies the requirement pyqt5-tools (from versions: none)
  
  ERROR: No matching distribution found for pyqt5-tools
  </code></pre>
  
  <p>I need to download pyqt5-tools because I am trying to learn how to make GUIs with PyQt (I am a beginner programmer). </p>
  
  <p>I have tried downloading different packages but anything related to PyQt has failed... It happens on both my Mac and Ubuntu machine.</p>
  
  <p>I have checked that the packages are available on PyPI and literally copy-pasted the install command from the website into the terminal to make sure that I did not do it wrong.</p>
