Using an extra python package index url with setup.py

Question

Is there a way to use an extra Python package index (ala pip --extra-index-url pypi.example.org mypackage) with setup.py so that running python setup.py install can find the packages hosted on pypi.example.org?

Answer 1

If you're the package maintainer, and you want to host one or more dependencies for your package somewhere other than PyPi, you can use the dependency_links option of setuptools in your distribution's setup.py file. This allows you to provide an explicit location where your package can be located.

For example:

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

If you host your own index server, you'll need to provide links to the pages containing the actual download links for each egg, not the page listing all of the packages (e.g. https://pypi.example.org/pypi/somedep/, not https://pypi.example.org/)

Answer 2

setuptools uses easy_install under the hood.

It relies on either setup.cfg or ~/.pydistutils.cfg as documented here.

Extra paths to packages can be defined in either of these files with the find_links. You can override the registry url with index_url but cannot supply an extra-index-url. Example below inspired by the docs:

[easy_install] find_links = http://mypackages.example.com/somedir/              http://turbogears.org/download/              http://peak.telecommunity.com/dist/ index-url = https://mypi.example.com
