Global gunicorn and pipenv virtual env: ModuleNotFoundError: No module named 'django'

I'd like to have gunicorn only installed globally (apt-get gunicorn3, Ubuntu 18.04) but recognizing my virtual environments managed by pipenv.

This works - local gunicorn:

# install dependencies from requirements.txt
$ pipenv install

# add local gunicorn
$ pipenv install gunicorn

# run the app, using local gunicorn
$ gunicorn my-site.wsgi:application

This doesn't work, and that's what I really need:

# install dependencies from requirements.txt
$ pipenv install

# activate the virtual environment
$ pipenv shell

# run the app, using global gunicorn
$ gunicorn3 my-site.wsgi:application

Error:

ModuleNotFoundError: No module named 'django'
[2020-03-18 17:04:31 +0000] [33871] [INFO] Worker exiting (pid: 33871)

As I have multiple python apps in the same server, and some of them cannot be modified to have gunicorn as a requirement, being able to run gunicorn3 globally and start more than one application with pipenv would be very convenient.

What am I missing to be able to run gunicorn globally but still load packages installed in a virtual environment?

I had the same problem and found it was caused by a -s in the shebang of /usr/bin/gunicorn:

#! /usr/bin/python3 -s

The -s causes the apt-get-installed gunicorn not to use the venv. man python3 says:

-s Don't add user site directory to sys.path.

So just override the shebang by running:

/usr/bin/python3 gunicorn my-site.wsgi:application

pipenv run gunicorn my-site.wsgi:application

instead of
