i have been trying using pip to install it just like everything else. i am just learning how to code so i dont understand what any of this means.

i have been trying to paste the error message into google and test the various solutions but neither installing it again, updating it, installing it directly where the scripts are worked. honestly i dont remember everything i tried but those are about the solutions the internet had provided. i have no idea if it is of any use but im using: python 3.12.2 pip 24.0 cython 3.0.9
