Please remember that initally our PyQt5 packages were for Python 3 only.
We have added Python 2 packages only to help other applications (like Calibre)
porting from PyQt 4 to PyQt 5. I do not recommend using Python 2 in new code.

I will not do this. If you just need to use pyuic with Python 2 then you may
just use “python2 -m PyQt5.uic.pyuic command” which needs only python-pyqt5.

What I can do is to replace a dependency on python3 with a recommendation —
as two of three tools in this package are written in C++ and do not need Python
at all. Let me know if this will help you.
