Formerly with setuptools, a Python dependency that needed to be installed from an extra index URL could just be added to dependency_links. Example from the answer here:

from setuptools import setup

setup(
    name='somepackage',
    install_requires=[
        'somedep'
    ],
    dependency_links=[
        'https://pypi.example.org/pypi/somedep/'
    ]
    # ...
)

But now that dependency_links is ignored, how do I install a package from a different index url with setuptools? The docs basically say to use VCS or dependency_links, but I'm unable to use the former and the latter doesn't work anymore.

    I don't think this specific question has been asked in the past 3 years since dependency_links has been deprecated. For example, the linked question I posted has people following up asking how to do it now. Any advice on how to deal with this differently? Commented Aug 16, 2021 at 22:17
  • @TrentMcCormick You can list extra URLs in the pip command line, environment variables or configuration files. You cannot list them in setup.py. Commented Aug 17, 2021 at 14:45

    Some pointers: stackoverflow.com/a/57704447 (read the comments as well) -- stackoverflow.com/a/58708235 -- stackoverflow.com/a/57978269 -- stackoverflow.com/a/66909248 -- stackoverflow.com/a/67344547 -- Sorry, I don't seem to find a good comprehensive canonical answer. -- Basically you should assume that dependency_links does not exist, it is now considered as somewhat of a "misfeature", and nowadays the user doing the install should be in charge of choosing the indexes, and not the creator of the package.
