dj-database-url | Use Database URLs in your Django Application | Database library

Okay, how I fixed this:

1. Make sure there is nothing funky to do with GDAL in your settings.py - I had followed this answer to get GDAL working on my local server during development and had to delete it the Paths from my settings.py
2. pip uninstall GDAL
3. pip freeze > requirements. txt
4. Add the heroku-geo-buildpack (link) and make sure it is set as the first buildpack for your app
5. git commit all your changes
6. Push the app again

Implicit relative imports are not anymore supported as documented:

There is no longer any implicit import machinery

So if Google.py is in the same directory as the code you pasted, you have to reference it's realtive location explicitly.

In Django, the gettext_lazy(…) function [Django-doc] is often imported as _ to manage translations. This is explained in the Standard translation:

Python’s standard library gettext module installs _() into the global namespace, as an alias for gettext(). In Django, we have chosen not to follow this practice, for a couple of reasons

(…)

Because of how xgettext (used by makemessages) works, only functions that take a single string argument can be imported as _:

• gettext()
• gettext_lazy()

You thus should add:

Here's the problem:

In your current requirements.txt you marked pywin32 with environment marker platform_system == "Windows". I think the syntax is wrong. The correct syntax from PEP 496 is:

The error occurred because you have installed your dependencies using Sudo. This has installed your pip dependencies only for Sudo users, whilst you are running your Django application as a non-sudo user. This is the reason why you didn't saw your packages when you did pip freeze but you saw them after doing sudo pip3 freeze

To solve this

1. Install python3-venv with this command sudo apt-get install python3-venv
2. Create a virtual environment python3 -m venv env this command will create a virtual environment named env
3. Activate the virtual environment with this command source env/bin/activate

Once you have done this you will see a (env) before your shell which indicates that your virtual environment is activated now need to install the dependencies inside this

1. cd to your requirements.txt and type pip3 install -r requirements.txt make sure you do it without sudo (because you will run your Django app in your web server as a non-sudo privilege user for security reasons)

After this, you can run your Django app with your virtual environment kept active.

You can remove the ports section for azurite service in your compose file and in your application provide the connection string and specify the blob endpoint (as mentioned here: https://docs.microsoft.com/en-us/azure/storage/common/storage-use-azurite#connection-strings) as BlobEndpoint=http://azurite:10000

When you use docker local bridge (created for services where deployed using compose), container name if provided explicitly else the service name can be used to access the service.

If you are using django-heroku package than you have to add this in your settings.py

Add the following import statement to the top of settings.py:

I had both a Pipfile and a requirements.txt in my project. Heroku seems to default to reading the Pipfile to find dependencies. I was only using requirements.txt to list my dependencies, and my Pipfile did not list any.

Solution: Deleted Pipfile and everything worked perfectly!
