Getting Qt5 version from the Python wheel

The change to Qt6 has broken Anki on my computer in 2.1.51, because I run a distro without systemd or Qt6. Previously I have been using the Python wheel to run Anki, which works fine for 2.1.49. Not so with 2.1.51.

I used pip install --upgrade aqt to install Anki (it mysteriously vanished today, hence why I noticed this issue so quickly after the release) and got the following error when attempting to run pyenv/bin/anki:

Traceback (most recent call last):
  File "~/programming/python-math/lib/python3.9/site-packages/aqt/qt/", line 13, in <module>
    import PyQt6
ModuleNotFoundError: No module named 'PyQt6'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "~/programming/python-math/bin/anki", line 5, in <module>
    from aqt import run
  File "~/programming/python-math/lib/python3.9/site-packages/aqt/", line 45, in <module>
    from aqt import gui_hooks

    from PyQt5.QtCore import *  # type: ignore
ModuleNotFoundError: No module named 'PyQt5'

(my home directory name/username has been obfuscated with ~ but other than that this is unedited)

So, I am curious: am I able to indicate to the Python wheel somehow that I want the Qt5 version? As I am unable to use the packaged releases due to their systemd dependency.

PyQt wheels depend on systemd. If you’re providing your own PyQt then you’ll need to use the same instructions as for Linux (ARM):
