pip is trying to build from source because there are no pre-built wheels for your system and python 3.13. Unfortunately most packages will not have those for 32-bit systems any more. One option is to downgrade your python version and use older packages. Looking back through the releases, I think the newest Matplotlib that supports 32-bit Windows is Matplotlib 3.7.5, which has wheels for python 3.11. So if you install python 3.11 and then do

python -m pip install matplotlib --prefer-binary

you should have more luck.

Thx for the quick response! Yep, 32bit Win10 is rare nowadays. Will give 3.11 a try and report back.

Python 3.11 works.
