I am running on ubuntu with several python versions installed. What am I missing?

user@serverA:/folderB$ python3.9 -m pip install numpy
Defaulting to user installation because normal site-packages is not writeable

Traceback (most recent call last):

Try running python3.9 -m pip install -U --user numpy. -U means upgrade, and --user means it'll install in your user folder, not the system folder - it just gets rid of that message.

NumPy is up to version 1.22, so it's possible that pandas just doesn't work with the old version.

I made a stupid mistake - I forgot to include install after the word pip. Check my answer now, it's correct.
