macOS + QGIS 3.44.6: ModuleNotFoundError: No module named 'PyQt5.QtWebKit' on plugin load (classFactory)

[GiorgiaStoppa]

Hi!
I’m having trouble loading DataPlotly on macOS with QGIS 3.44.6.

What happens

When enabling/loading the plugin, QGIS fails with an error during classFactory() and the traceback includes:

ModuleNotFoundError: No module named 'PyQt5.QtWebKit'

It looks like the plugin (or some dependency) is importing QtWebKit (PyQt5.QtWebKit / qgis.PyQt.QtWebKit)

Environment

OS: macOS

QGIS: 3.44.6

Steps to reproduce

Install QGIS 3.44.6 on macOS

Install DataPlotly from the QGIS Plugin Manager

Enable the plugin / restart QGIS

Plugin fails to load with PyQt5.QtWebKit missing

Thanks!

I think you should install webkit on your computer manually. Not sure what is the best procedure on a macOS. I'm working on the transition to webengine and Qt6, but we have to wait for QGIS 4 ;)
