setuptools - How to include and install local dependencies in setup.py in Python?

Question

I am creating a setup.py to distribute my application. This application has a number of dependencies which can be installed via pip, it also has some custom dependencies which can not be installed from PyPI.

So, I have created a custom_package_0.1.whl which will be included into the distribution and must be installed as a dependency after setup.py installs everything from install_requires.

Imagine the following app structure:

my_app/
    win_deps/custom_package_0.1.whl
    my_app/
        __init__.py
        main.py
        setup.py
        setup.cfg

How do I do that?

There is a new technique (Since version 19.1) called Direct references. Just pretend like your file is hosted on localhost.

from setuptools import setup

path_to_my_project = "/home/user/projects/my_package"  # Do any sort of fancy resolving of the path here if you need to


setup(# ... other arguments
      install_requires=[f"my_package @ file://localhost/{path_to_my_project}#egg=my_package"]
      )
