Django application (Wagtail CMS Bakery demo) as Python zipapp using Shiv

gistfile1.txt

I ran into a couple of problems following the example on the Shiv (RTD) docs page 

The following files worked for me from a python3 virtual env called test_shiv_env

Created .py file  
test_shiv_env/bakerydemo/bakerydemo/main.py


import sys

import django

def main():
    # setup django
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "bakerydemo.settings.dev")
    django.setup()

    try:
        production = sys.argv[1] == "production"
    except IndexError:
        production = False

    if production:
        import gunicorn.app.wsgiapp as wsgi

        # This is just a simple way to supply args to gunicorn
        sys.argv = [".", "bakerydemo.wsgi", "--bind=127.0.0.1:8000"]

        wsgi.run()
    else:
        from django.core.management import call_command

        call_command("runserver")
        
        
        
        

Then I created build.sh file
test_shiv_env/bakerydemo/build2.sh


#!/usr/bin/env bash
project_name=bakerydemo

# clean old build
rm -r dist ${project_name}.pyz

# include the dependencies from `pip freeze`
pip install -r <(pip freeze) --target dist/

# or, if you're using pipenv
# pip install -r  <(pipenv lock -r) --target dist/

# specify which files to be included in the build
# You probably want to specify what goes here
cp -r manage.py dist
cp -r ${project_name}db dist
cp -r ${project_name} dist

# finally, build!
shiv --site-packages dist --compressed -p '/usr/bin/env python3' -o ${project_name}.pyz -e ${project_name}.main:main



Make sure you have the wsgi.py 
test_shiv_env/bakerydemo/bakerydemo/wsgi.py

"""
WSGI config for portal project.

It exposes the WSGI callable as a module-level variable named ``application``.

For more information on this file, see

import os

import dotenv
from django.core.wsgi import get_wsgi_application


dotenv.read_dotenv(os.path.join(os.path.dirname(os.path.dirname(__file__)), '.env'))

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "bakerydemo.settings.dev")

application = get_wsgi_application()
