Issue Description

I am getting the following error when attempting to build the docs with python make.py html:

I have had a similar issue before #53788 but this is slightly different. I updated mamba, updated the pandas-dev environment, and built pandas before running this so I don't know what would be out of date. I'm on WSL 2 FYI.

Expected Behavior

Expected the docs to build in html/

Hi,

I had experienced almost the same issue and reported it in #54212, but the problem vanished for me last time I tried. I haven't tested it since.

Can you check whether the issue is present for you when you checkout commit 01c3e8b?

Thanks!

Thanks for your comment @DavidToneian.

It seems like when I try to run things from that commit, I can't even get make.py to run:

Not sure what's going on here either.

Just an update: I checked this again on 28f274cb10 and the issue persists.

I think this has gone stale. If the issue persists, comment here and we can reopen.
