Check if my Python has all required packages

Question

I have a requirements.txt file with a list of packages that are required for my virtual environment. Is it possible to find out whether all the packages mention

Answer 1

If you're interested in doing this from the command line, pip-missing-reqs will list missing packages. Example:

$ pip-missing-reqs directory
Missing requirements:
directory/exceptions.py:11 dist=grpcio module=grpc

(pip check and pipdeptree --warn fail only audit installed packages for compatibility with each other, without checking requirements.txt.)
