    I'm not familiar with these pip options, but I tried this and got the
    following output:

    Using pip 25.2 from C:\Python313\Lib\site-packages\pip (python 3.13)
    ERROR: Could not find a version that satisfies the requirement
    matplotlib (from versions: none)
    ERROR: No matching distribution found for matplotlib


This means that pip can't find matching wheels. You would see this error message at the end if you didn't have a network connection. Assuming pip can reach pypi then it thinks that none of these wheels is suitable:

https://pypi.org/project/matplotlib/#files

There seem to be wheels for 3.13 on Windows for amd64 and arm64.

Is it possible that you are on a 32 bit machine or using a 32 bit build of python?

I'm using a 32-bit build of python:

>python
Python 3.13.3 (tags/v3.13.3:6280bb5, AprĀ  8 2025, 14:32:59) [MSC v.1943 32 bit (Intel)] on win32
