Django Error: django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module

Question

I'm new to Python and Django, And I'm trying to run a Django app which uses MySQL as a database,
I installed mysqlclient using pip, which it shows as Requirement already satisfied: mysqlclient in ./env/lib/python3.7/site-packages (1.4.4)

But when I run the project or try to create a superuser,
it throws me the following error -

Aniruddhas-MacBook-Pro:python_django aniruddhanarendraraje$ ls
djangocrashcourse-master        env                             projectNameHere

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

After adding the following to __init__.py-

import pymysql
pymysql.install_as_MySQLdb()

I already have MySql in my computer, which I'm using in other languages, will this override my Db settings or just add a python client for MySql? — Dev1ce

Install mysqlclient on virtualenv by which you run your django project

Install mysqlclient and pymysql

pip install pymysql
pip install mysqlclient==1.4.4

Then add following lines on project root (belong with settings.py) __init__.py

import pymysql
pymysql.install_as_MySQLdb()

Example project structure

├── manage.py
├── stackoverflow
│   ├── __init__.py
│   ├── settings.py
│   ├── urls.py
│   └── wsgi.py
└── templates

I add these import pymysql pymysql.install_as_MySQLdb() in __init__.py file?

shafikshaon Over a year ago

Yes. these 2 lines in __init__.py

Dev1ce Over a year ago

Now I'm getting a django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 0.9.3.

shafikshaon Over a year ago

I have installed an old version. Install the new version by pip install mysqlclient==1.3.13

Dev1ce Over a year ago

did pip install mysqlclient==1.4.4 but getting the same error, do I need set any PATH or something?
