Did you run pip install -r requirements-docs.txt in your virtualenv? The versions of Sphinx and its dependencies are quite specific for these docs. It works for me locally and on ReadTheDocs so I'd look there first.

[sierzput]

Yes, I installed requirements-docs.txt in my virtualenv. Problem is fixed when I updated dependencies from requirements-docs.txt to the latest versions. It looks like an issue with some dependency, probably on Python 3.10. Which Python version do you use @scanny ?

[scanny]

My local virtualenv for python-docx has Python 3.8.18 installed. I expect that was on purpose because I got a new machine a few months ago, and I vaguely remember downgrading it for the purpose of building the docs.

[sierzput]

I think it would be good to update soon anyway, because the end of support for Python 3.8 is October 2024.

[scanny]

Yeah, at some point ReadTheDocs won't support that version anymore and we'll be forced to update I suppose. Switching to the new templates will require pretty broad changes I expect so that's not going to be a quick job :)

The docs aren't really something designed for folks to build for themselves. I don't even use them locally myself, I always go to ReadTheDocs to consult them. But I suppose if you were working offline for some reason that might be handy.
