How to Fix the \'Error Loading MySQLdb Module\' in Django on Windows 10?

Troubleshooting the "Error Loading MySQLdb Module" Issue in Django with MySQL

When working with Django projects on Windows 10 using Python 3.4, users may encounter difficulties with MySQL connectivity. The following error message often accompanies this issue:

django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: No module named 'MySQLdb'.
Did you install mysqlclient or MySQL-python?

Understanding the Issue

This error indicates that Python cannot find the MySQL database module, MySQLdb, which is required for Django to connect to the database. The message also prompts you to ensure that either mysqlclient or MySQL-python is installed, as both offer MySQL support for Django.

Resolving the Issue

To resolve this issue effectively, follow these steps:

1. Install PyMySQL: Execute pip install pymysql from the command line to install the PyMySQL package. This module serves as a Python wrapper for MySQL's C API and can be used as a replacement for MySQLdb.
2. Edit the __init__.py File: Navigate to the origin directory of your Django project (where the settings.py file is located) and open the __init__.py file. Add the following lines of code:

import pymysql

pymysql.install_as_MySQLdb()

These lines ensure that PyMySQL is installed and loaded into Python's sys.modules, effectively replacing MySQLdb.

Once these steps are completed, rerun the python manage.py migrate command. This should successfully migrate the tables to the MySQL database and resolve the "Error Loading MySQLdb Module" issue.
