Error installing Mysql and connect to Django

Question

I try to connect MySQL on my django project, but I still have error:

django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module.
Did you install mysqlclient?

For more information I use Fedora 31, virtual env in python3.7.7, and when I try to install Mysql pip3 install mysql, mysql-python, pymysql...

If you have any idea for helping me, I take it. Thanks in advance.

Answer 1

It's a problem of C files compilation.

I should do:

sudo dnf install python3-devel

and for python2:

sudo dnf install python2-devel
