What's the difference between Python pip's pip.conf and pypirc file?

I'm having trouble reaching a nexus server that we're using to store custom python packages. I've been told to change the settings in both my ~/.pypirc file and the ~/.pip/pip.conf file.

~/.pypirc

~/.pip/pip.conf

What's the difference between those two files in how they're used? It seems like the pip install -r requirements.txt command refers to the pip.conf file, and then the fields within the pip.conf file requires looking up the pypirc file?

pip install -r requirements.txt

pip.conf

pip.conf

Example pip.conf file:

[global]
index = https://user:password@someurl.com/somerepo/pypi-group/pypi
index-url = index = https://user:password@someurl.com/somerepo/pypi-group/simple


Example pypirc file:

[distutils]
index-servers =
pypi
nexus

[pypi]
repository: https://pypi.org/pypi
username: abc
password: def

[nexus]
repository: https://someurl.com/somerepo/pypi-internal
username: someuser
password: somepassword


Also, what's the difference between index and index-url in the pip.conf file?

.pypirc is a file standard used by multiple tools, not just pip. For example, the easy_install tool also reads that file. It contains configuration on how to access specific repositories

.pypirc

pip

easy_install

pip.conf on the other hand is only used by the pip tool. It may use information from .pypirc if authentication is needed when installing from a specific PyPI index server.

pip.conf

pip

.pypirc

However, the .pypirc file is more commonly consulted when publishing packages, not when installing.

.pypirc
