NameError: name '_mysql' is not defined - Django tailwind

When I run python manage.py runserver, my django server runs and I can see my webpage, however some of the tailwind doesn't work.
When I then stop that server and run python manage.py tailwind start, the localhost:8000 doesn't show my webpage, but my terminal says that it is running.
When I then stop the tailwind server running, and run python manage.py runserver, I get an error saying NameError: name '_mysql' is not defined.
I am unsure why this is happening, here is my full stack trace:

I also encountered the same error last few days, just found this solution and it works for me, hope it helps!
Use the following command to check mysqlclient is installed or not: pip freeze
Add env variable to ~/.zshrc for zsh, or ~/.bashrc or
~/.bash_profile for bash etc.):
export DYLD_LIBRARY_PATH=/usr/local/mysql/lib/
Apply change by running
source ~/.your_shell_config_file

Did you install mysqlclient?
Here, is part of my settings.py
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'first_django_project',
'USER':'root',
'PASSWORD':'root',
'HOST':'localhost'
}
}
And I used the following command for connector
pip install mysql-connector
I am trying this:
https://pypi.org/project/mysql-connector/
I am yet to try this approach:
https://dev.mysql.com/doc/connector-python/en/connector-python-django-backend.html
So, what is the mistake I am doing here, or is the whole approach wrong? Please, help me.
Thanks

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)

Why Django tries to use MySQL instead of sqlite3

My problem is this: When I try to do the migrations, it gives me the following error:

django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module.
Did you install mysqlclient?
Thing is, I've never told django to use MySQL, in fact, the settings.py states that it has to use SQLite:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(BASE_DIR, 'gestlote.db'),
}
}
I've alreay tried to reinstall django, upgrade it, pip3 install pysqlite, but nothing seems to work.
So please, help me

Run pip install mysql-python before making any migrations.
