title: python3 install pyqt5 sip ubuntu
body: <p>I am installing PyQt5 using 'python3 configure.py --sip sip-4.19.13' in ubuntu. If I install manually sip4.19.13 then I get the error:</p>
  
  <pre><code>Error: /usr/include/python3.6m/sip.h has version 4.19.7 but /usr/bin/sip has version 4.19.13.
  </code></pre>
  
  <p>Instead if I install sip4.19.7, then running 'python3 configure.py --sip sip-4.19.7':</p>
  
  <pre><code> Error: This version of PyQt5 requires sip 4.19.11 or later.
  </code></pre>
  
  <p>What should I do? Any help appreciated</p>
