ImportError: cannot import name '_PosixFlavour' from 'pathlib'

AUR package maintainer here. I've updated everything now that Python 3.12 is available in Arch, however...

same error. maybe this can help https://github.com/hadialqattan/pycln/issues/221 (they had the same issue)

same error. maybe this can help hadialqattan/pycln#221 (they had the same issue)

That is exactly what causes this issue. Installing aiopath v0.7.1+ fixes this problem. Requested python-aiopath maintainer update this package.

I tried aiopath 0.7.1 and 0.7.6, now there's a different error:

@yochananmarqos this might be some other issue not related with aiopath. With aiopath 0.6.11 you get this:

$ cast_control --help

ImportError: cannot import name '_PosixFlavour' from 'pathlib' (/usr/lib/python3.12/pathlib.py)

With 0.7.1 and 0.7.6

@BanditSan Yes, you're right. I manually created the ~/.local/state/cast_control/0.14.0/ folder and the files were able to be created. It seems to be attempting to work now.

Anyway, I've updated the python-aiopath AUR package to 0.7.6.
