One issue here seems to be that even if the main script is launched with python3, the actual server via uwsgi can still launch under python2!

Torsten installed uwsgi via pip (for python2) and not via pip3. Still, the error message is horrible.

Should be fixed in c93ad0e..a1f8eb2: better error on uwsgi not found, plus check for Python 3.6 early on.
