`collectstatic` error when deploying Django app to heroku - django

Question

While deploying my Django app to heroku, but colletstatic method seems to throw lots of errors. I've tried several solutions posted online but none worked. By the way, I'm using whitenoise for serving my static files.

Answer 1

It's looking in the directory Nostradamus/static and throwing an error because that directory doesn't exist.
If that directory does exist locally then the problem might be that it's empty and so git doesn't track it. The simple solution to that is to create an empty file called .keep (or anything you like, it doesn't matter what it's called) in that directory which will cause git to "see" it.
