How do i solve this: ModuleNotFoundError: No module named 'africastalking'

Hi Anthony, thank you so much for this excellent tutorial.

I'm stuck with building an image from a Dockerfile. Please, help me on how to go about this.

Advise also where the Dockerfile should be and if it should be in the virtual environment as well. Help me also understand if the the app.py and the requirements.txt also should be in the virtual environment.

Looking forward to your support.

It is my first time creating a flask app and deploying a docker container to Heroku. This article explains it nicely, thank you. I got this error (no basic auth credentials ▸ Error: docker push exited with Error: 1)

this helped me solve it github.com/fiorix/freegeoip/issues/171

If you find any issues, don't mind raising them in the comments. Would love to make this article as accurate as possible. :)
