title: UWSGI fails to install on Debian 9 (pip)
body: <p>I've already installed all necessary libraries even did <code>apt-get build-dep uwsgi</code> but I think I have problems with system libraries.</p>
  
  <p><strong>No I can't use pre-built uwsgi package for Debian because some project libraries depends on pip version.</strong></p>
  
  <p>Any suggestions?</p>
