Thank you, problem solved :)

If sudo apt install python3-dev doesn't work, you could try sudo apt install python3.8-dev which works for me.

If you're using Anaconda, then
conda install psutil
did the job for me (I tried all other solutions suggested here and this is the only way I got it to work for my python version of 3.8)
