Failed to run locally on Windows

[v-jiaodi]

Describe the issue: When test Running locally on Windows, run python -m gunicorn project.wsgi:application --pythonpath src --reload, get error as follow:

Repro Steps:

1. Clone the repo to local.
2. Create a Python virtual environment and activate it.
3. Install requirements: python -m pip install -r src/requirements.txt
4. Apply database migrations and seed initial data: python src/manage.py migrate python src/manage.py loaddata src/seed_data.json
5. Running Locally: python src/manage.py collectstatic python -m gunicorn project.wsgi:application --pythonpath src --reload

Environment:

• OS: Windows.
• Azd version: 1.4.1 (commit https://github.com/Azure/azure-dev/commit/1cbed85cf47ed235b5ed31868eda79619525bfcc)
• Python : 3.9
• Template: https://github.com/Azure-Samples/azure-django-postgres-flexible-aca https://github.com/Azure-Samples/azure-django-postgres-flexible-appservice https://github.com/Azure-Samples/azure-django-cosmos-postgres-aca https://github.com/Azure-Samples/azure-django-cosmos-postgres-appservice https://github.com/Azure-Samples/azure-django-postgres-addon-aca https://github.com/Azure-Samples/azure-flask-postgres-flexible-aca https://github.com/Azure-Samples/azure-flask-postgres-flexible-appservice https://github.com/Azure-Samples/azure-flask-cosmos-postgres-aca https://github.com/Azure-Samples/azure-flask-cosmos-postgres-appservice https://github.com/Azure-Samples/azure-flask-postgres-addon-aca https://github.com/Azure-Samples/azure-flask-cosmos-mongodb-aca https://github.com/Azure-Samples/azure-flask-cosmos-mongodb-appservice https://github.com/Azure-Samples/azure-fastapi-postgres-flexible-aca https://github.com/Azure-Samples/azure-fastapi-postgres-flexible-appservice https://github.com/Azure-Samples/azure-fastapi-cosmos-postgres-aca https://github.com/Azure-Samples/azure-fastapi-cosmos-postgres-appservice https://github.com/Azure-Samples/azure-fastapi-postgres-addon-aca

Expected behavior: Please confirm if it can be supported on Windows. If so, it is expected that Run locally will pass.

@pamelafox for notification.

Interesting, I didn't realize gunicorn didn't work on Windows. It should work inside a Dev Container in VS Code in Windows. We can probably figure out commands for each framework that will work locally on Windows - flask has its own dev server, django has its own dev server, and fastapi can be run with uvicorn. Thanks for the report! @kjaymiller

@v-jiaodi can you try to run locally again?

[v-jiaodi]

@kjaymiller The issue still exists.

[pamelafox]

@v-jiaodi Can you confirm that you tried the new instructions in the updated README?

https://github.com/Azure-Samples/azure-django-postgres-flexible-aca#running-locally

It now says:

python3 src/manage.py runserver 8000

That does not use gunicorn, so I hope is that it works for you.

@pamelafox It works with the new instructions python3 src/manage.py runserver 8000.

The following templates still has this issue:

• https://github.com/Azure-Samples/azure-django-cosmos-postgres-appservice
• https://github.com/Azure-Samples/azure-django-postgres-addon-aca
• https://github.com/Azure-Samples/azure-flask-postgres-flexible-aca

@v-jiaodi We have merged the README updates to those repos. Can you take a look and confirm that works for you?

[v-jiaodi]

It works.
