I'm writing a (really janky) 2d fluid simulation in Python. Currently I'm generating a starting state for the sim by just filling a 2d array with random floats generated by the random module, and then blurring the texture by averaging each cell with the ones around it. This is very slow, and produces a noise texture that's somewhat blocky due to the square blur shape. So once I got bored of waiting for ten seconds every now and then for python to generate a new random grid, I decided to invest what I thought would be a mere ten minutes into figuring out how to use a library for it. Five hours later, I find myself exactly where I started, just more frustrated. I've been trying to install this package using the command pip install noise, but every time I try the command the same error comes back, even after trying every other fix for similar problems I could find. The error looks like this:
Defaulting to user installation because normal site-packages is not writeable

I've tried updating wheel, setuptools, Cmake, pip, Python, and even PowerShell to no avail. I've added all the python-related dirs to PATH as well. Nothing has worked, I still get the same error.
The package you are trying to install contains C code and thus needs to be compiled.
You have an issue with your toolchain though:
You are using a x86 compiler/linker, see HostX86\x86\cl.exe and ...HostX86\x86\link.exe - make sure that you have a 64 bit python and that you execute C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build\vcvars64.bat before attempting your pip install
Apart from that, you might have compatibility issues:
The library you are trying to install was last updated in 2015. It looks to me like the missing symbols should be present in python 3.12 as well, but no guarantee that installing to this python version will work without issue. If, after making sure you are compiling for x64 you still have issues, try to downgrade python to a lower version
