I have the same issue and I found the reason is django-mssql support Django 1.8 but you are using Django 1.11. Please downgrade your Django version or wait until the latest version will be supported.

I am a beginner in python and Django.
I would like to connect my Django project to MySQL database,I have installed mysqlclient
brew install mysql
pipenv install mysqlclient
but after changing the settings to:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'storefront',
'HOST': 'localhost',
'USER': 'root',
'PASSWORD': 'my_password',
}
}
I get an error for running server: (NameError: name '_mysql' is not defined)

Also I have added the directory of MySQL to the PATH
echo $PATH
export PATH=$PATH:/opt/homebrew/opt/mysql
What's the problem then ?
I'm using python 3 and I have tried to connect my Django project(django3) to MySQL but I keep getting this error even though I installed mysqlclient.

django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module.
Did you install mysqlclient?
Make sure you are running the MySQL server on your machine.
Then find out you installed mysqlclient package on your system, you can install it using this command:
pip install mysqlclient
then add this config to your settings.py:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'DB_NAME',
'USER': 'DB_USER',
'PASSWORD': 'DB_PASSWORD',
'HOST': 'localhost'
'PORT': '3306',
}
}
According to https://github.com/Miserlou/lambda-packages You will get this error because there's no mysqlclient built for Python 3.7. Therefore you have to use pymysql.
I have figured out a way to fix this issue by,
First, you have to install pymysql
pip install pymysql
Then you have to add this code into init.py(or settings.py) file
import pymysql
pymysql.install_as_MySQLdb()
pymysql.version_info = (1, 3, 13, 'final', 0)
This Django project is working before I created another Django project on my computer. But today when I run the project it shows error message like that=>

django.core.exceptions.ImproperlyConfigured: Django 3.0.1 is not supported.
What is mean Django 3.0.1 is not supported?
The sql_server package you're using isn't compatible with Django 3.0 or higher. It's not clear from your question which sql_server package you're using (is it django-pyodbc?) but most of the packages haven't added support for Django 3.0 yet.
Use a version of Django that is compatible with you django-pyodbc package (consult the documentation of the package, probably you should be using Django 2.1 or 2.2) or fork the package and modify it to support Django 3.0.
your problem is due to installing different version for your new project.you should use a different virtual environment for each project to avoiding this problems.
Can you please create virtualenv using python3.7.3 then install Django3 inside virtualenv. Because Django3 support only Pyth on3.6 and upper. Maybe some python version compatibility issue is there. for python version change please follow this link .. https://unix.stackexchange.com/questions/410579/change-the-python3-default-version-in-ubuntu
I have a problem in connect mysql wamp to django using mysql connector

Did you install mysqlclient?
First activate the virtual environment and then do,
pip install mysqlclient
