Spyder fails to load after QtWebEngine update

[MLXQt]

Hi,

i use Manjaro LXQt (both last update). After QtWebEngine last update, Spyder fails to load.

Here the output:

Traceback (most recent call last):

    )
RuntimeError: PyQt5.QtWebEngineWidgets cannot import type '����' from PyQt5.QtCore

Anybody has a solution and can explain? Is this a problem have i to report to LXQt GitHub too?
Thanks.

Could be related to Qt5 vs Qt6 but I have no idea - a search - maybe an oversight from upstream Arch Linux?

Perhaps you can work around it with python-pyqt5-webkit package from AUR.

Yes I know - spyder is in the repo - but did you install from other source.

Hi, i installed Python and Spyder from repo.

python-pyqt5 (repo) and python-pyqt5-webengine (AUR) installed too.
I’m using Spyder with miniconda3 now, but it’s not convenient because I’d have to reinstall all the packages I use.

python-pyqt5-webengine

It would seem you need another custom package to replace it - possibly python-pyqt5-webkit package.

EDIT: Is the webkit package different from webengine package ?

To be honest i don’t know but i guess yes.

Anyway, I installed the python-pyqt5-webkitas You said and now Spyder
loads.
Thanks.
