Error trying to install scikit-Learn

Question

I’m trying to install scikit-Learn via Pip to python 3.9, but in the part that says "Installing build dependencies..." an error occurs every time. I have already installed numpy and scipy, which are prerequisites, and I have even formatted my PC, but it still gives the error. The error message is very big, but these are the initial and final lines, which I believe are the most important:

Answer 1

Try to update setuptools

pip install --upgrade setuptools

If it doesn’t work out, send the whole mistake if there’s more.
