Spyder - IDE for Python - asks for package not in reps

I've very recently fully upgraded my system (with "pacman -Syu") and installed spyder from the standard "extra" rep.  But when spyder starts, it asks for the package "pylsp_ruff", which (under that name) is neither in the standard reps, nor in the AUR.  There are various "python-ruff" packages, but it's not clear which (if any) would be correct here.  Same for "python-lsp". 

The spyder docs recommend either using conda, or installing directly from its own repository.  I can do these (either of them) - miniconda3 for example is available in the AUR - but of course I'd rather have my system managed by pacman as much as I can.

What's my best option here?

Thanks!

Please start spyder from terminal and post its output so we can see the exact message.

Re: Spyder - IDE for Python - asks for package not in reps

Thank you.

The terminal output is

notebook: The QtWebEngineWidgets module was not found. It must be installed separately as PyQtWebEngine.
Traceback (most recent call last):

    from PyQt5.QtWebEngineWidgets import (

    )
ModuleNotFoundError: No module named 'PyQt5.QtWebEngineWidgets'

The above exception was the direct cause of the following exception:

and the popup error is

You have missing dependencies!

# Mandatory:
pylsp_ruff >=2.3.0,<3.0.0 : None (NOK)

Please install them to avoid this message.

Note: Spyder could work without some of these dependencies, however to have a smooth experience when using Spyder we strongly recommend you to install all the listed missing dependencies.

Failing to install these dependencies might result in bugs. Please be sure that any found bugs are not the direct result of missing dependencies, prior to reporting a new issue.

Would it be better for me to communicate this via the package page at https://archlinux.org/packages/extra/any/spyder/?

Anyway, the app starts up fine, but it's the popup error which confuses me.

Thanks again.
