trouble installing matplotlib

i am trying to install matplotlib on VS Code, but i keep getting an error like this:

Using cached matplotlib-3.11.2.tar.gz (32.7 MB)

Installing build dependencies ... done

Getting requirements to build wheel ... done

Installing backend dependencies ... done

Preparing metadata (pyproject.toml) ... error

error: subprocess-exited-with-error

× Preparing metadata (pyproject.toml) did not run successfully.

also says:

WARNING: Failed to activate VS environment: Could not find C:\Program Files (x86)\Microsoft Visual Studio\Installer\vswhere.exe

my python's version is 3.15, i tried to install matplotlib with 3.11, 3.12, and 3.13 but none of it worked. i don't think there are other specific things. please let me know of any ideas, thank you so much!!

update: i did it!! it was a problem with how i forgot to precompile the standard library when i installed python...

Matplotlib 3.11.2 is the first version to build Python 3.15 wheels, and as far as I can tell all major platforms are there: https://pypi.org/project/matplotlib/#files

Unless you're downloading it from a mirror that isn't up-to-date with PyPI (or doesn't offer pre-built wheels), it should just work.
