Answer 1

I had the same error. I just uninstall Python3.8 and install Anaconda Python(3.7). I don't exactly what the problem is. But I guess 3.8 may have a dependency problem. If you use Python3.8. You can try this way.

Answer 2

Try to use an older version

pip uninstall pandas
pip install pandas==0.25.3
