WSGI django ModuleNotFoundError: No module named 'django' - django

Question

I have been trying forever to get my django api to deploy via apache. I have installed mod_wsgi for python 3.7 and my venv is using python 3.7.15. Trying to go to my django app url I am getting a 500 error.
Error log shows:

if path not in sys.path:
sys.path.append(path)
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project.settings')
application = get_wsgi_application()
I originally had the wrong mod_wsgi installed (built for python2). I removed that and installed python3-mod_wsgi.x86_64 and changed module path in httpd.conf. I then realized that my mod_wsgi was for python version 3.7, but my application venv was running python 3.6.8. I then wiped the venv and created a new one with python 3.7.15. Changed the conf WSGIDAEMONPROCESS path to the correct 3.7 site-packages. Still same error.

Just installing a virtual environment is not enough, then you'll have to activate it.
Run pip install -r requirements.txt to install the required packages for the project.
The Error
The first error line states Target WSGI script '.../project/project/wsgi.py' cannot be loaded as Python module.
This means your environment variable DJANGO_SETTINGS_MODULE is not set properly. In order to do it, go to .bashrc and set it to the same value as in the asgi.py/wsgi.py file.
Run source .bashrc to reload the configuration file, and restart the bash terminal (or open a new one) where you're trying to run the application.
This should work.
