Python - Django, Cannot install mysqlclient using pip

Question

I'm new to Django and I'm facing some issues installing mysqlclient for my application running this command

pip install mysqlclient

I'm getting an error ModuleNotFoundError: No module named 'pip._internal.operations.build.wheel_legacy'

Traceback (most recent call last):

I have Python 3.8.3 and pip 20.2.3

what is the cause of this error and how can I solve it?
