Installation problem

[Solomon Onuche Faruna]

I install python 3.8 and pycharm community edition on window 8 but when I
try to install matplotlib in pycharm I discovered I got  "error loading
package list pypi.python.org" so I updated the pycharm to version 2020.1.
The packages loaded but when I try to install matplotlib I was told "No
matching distribution found for matplotlib". I am confused right now. I
need urgent help. Thanks
