Is there a way to get directory package dependencies in python?

Question

I am aware that pip freeze > requirements.txt exists, yet that that prints out my system packages, of which only a few my directory/ project needs.

I am not using a virtualenv so I'm pretty sure I can't print out local packages like that.

I also know that pipdeptree exsists but I also don't see how that solves my problem?

Answer 1

I believe tools like the following could help:

• pipreqs
• pigar

As far as I can tell, these tools read the code in the directory and try to figure out the dependencies required based on the import statements they found in the code.
