Thanks for sharing these instructions in a public gist! 🙂

I installed Python 3.7.16 in my home using these commands. But trying to install psutil fails with an error:

$ /home/USERNAME/<LOCALPROGRAMDIR>/python3.7 -m pip install psutil
   ...
ModuleNotFoundError: No module named '_ctypes'

Some online sources suggest doing yum install libffi-devel - but I don't have sudo access. Do you have any idea how to solve this problem without sudo access?
