unable to install mysqlclient to connect django to mysql db on my mac

nac777 :

I'm new to mac, python and django. This will be my second project.

I use to have a django environment working on my old windows pc but, that also came with many weeks of struggle to get it working.

Now I've been struggling through article after article on the web but, with absolutely no progress for 2 weeks.

I just keep getting this issue.....

Uninstall python following this link https://macflypro.com/uninstall-guides/remove-python.html

Then reinstalled by going to terminal using this command:
