mysqlclient 1.4.3 or newer is required

This error message usually occurs when you are trying to install or use a Python package that requires mysqlclient version 1.4.3 or newer, but your current version is older than that. You can try upgrading mysqlclient to the latest version by running the following command:

pip install --upgrade mysqlclient

If you still encounter the same error message after upgrading mysqlclient, you may need to check if your MySQL server is properly installed and running, or if there are any compatibility issues between your Python version and the mysqlclient version you are trying to use.
