I've created a Python 3.6 environment in my WSL Ubuntu 22.04 operating system using virtualenv -p python3.6 <my_env>. I need to download some packages, particularly matplotlib, but I'm having some problems. When I run pip install matplotlib from terminal, it returns me ERROR: Command errored out with exit status 1, as it fails to build wheel for matplotlib, kiwisolver and pillow. I can't upgrade the Python version. I don't know what to do, I've tried everything I found online, but it's not working.
