How do I get local server running - here with language error message?

I have a Django app (with a postgres database) running in a virtual environment. Everything has been working on my localhost until a few days ago when I got an error saying my SSL certificate had expired (localhost:8000). Today, when I tried the python manage.py runserver command I got an error saying psycopg2 was not installed. I know it was because I have been using this app for the last nine months! Anyway, I reinstalled psycopg2 and tried the runserver command again. This time I got the following error message:
$ python manage.py runserver

Any ideas on what may be happening here? As I said, everything was working well until a few days ago, then the gremlins got in.

coverage using wrong python path, although venv is sourced

I am working on a Django project and trying to run the command coverage run --source='.' manage.py test myapp from the Django documentation. Somehow coverage uses a different python path than the virtual environment I am in (I guess that is the reason that the module is not found)
I get the following output:

To me the problem doesn't seem related to django or the python-decouple module, but coverage not using the python path of my sourced venv. I tried to search the docs from coverage but couldn't identify what function or method is used when running coverage run can somebody help me out on where to look or how to identify the problem?

This seems to be a conflict with your global python packages.
As your log suggests, coverage is from /Users/username/.pyenv/versions/3.7.2/.
And you want to use the /Users/username/project/venv/lib/python3.9/.
There are 2 ways to do this, uninstall global coverage.
(venv) $ deactivate
$ pip3 uninstall coverage
$ source venv/bin/activate
(venv) $ python -m pip install coverage
Or if you plan on keeping global package you can try this.
(venv) $ python -m pip install coverage
(venv) $ python -m coverage
This will get the packages with respect to /Users/username/project/venv/lib/python3.9/

ModuleNotFoundError: No module named 'polls.url'

First of all check if you have incorrect file names for apps in INSTALLED APPS in settings.py. Your app should be sthg like:
INSTALLED_APPS = [
'home.apps.HomeConfig' # or simply 'home' assuming all your app name,
......
]
Then, restart the server, if everything is good and still does not work.
In some cases the error is also shown because of migration. Try making migrations. Like:
python manage.py makemigrations
python manage.py migrate
You should be good to go by now.

Found it. Instead of polls.url, I wrote poll.url inside the url.py for the mysite package. Watch your spelling!

In my case, it was some corrupted migrations file. I deleted it and ran migrations afresh.

My folder in App was url.py
and in project setting i was writing path('', include('loginaccounts.urls')).
In path when I changed to url from urls it worked as it was not able to map the path.

Django projects with Postgres stopped working after brew install

I was trying to get Selenium to work, and so followed the suggestion here to brew install geckodriver in the relevant virtual environment (pipenv). After having done that, my other virtual environments stopped working.
I was able to get most of them to work again by re-installing pipenv outside of any virtual environment (using pip3 install pipenv).
But all of my Django projects that rely on Postgres still don't work: I'm able to start their virtual environment (with pipenv shell), but python manage.py runserver gives me the following traceback:

I have 'django.contrib.admin' among my INSTALLED_APPS. And, again, everything was working just fine prior to my geckodriver adventure.
Re-installing psycopg2 with pipenv install psycopg2 doesn't solve it. I've also tried uninstalling psycopg2, but when I then try to install it again, I get Locking Failed.
Any advice here on what's going on would be appreciated.
