Changed behavior with --extra-index-url with pip 9 #4195
Description
- Pip version: 9.0.1
- Python version: 3.5.2+
- Operating System: Debian Stretch (testing)
Description:
We have a private internal package we use for our projects that is hosted on our own internal server. That packaging server only has our private packages and is not a full PyPI mirror, because it's not what we need. In the past, I have been able to run:
pip install -r requirements.txt --extra-index-url http://pip.croscon.com:8088/simple/ --trusted-host pip.croscon.com
and it works fine. However, now when I run this command, I get an error from pip saying it can't find a specific package on pip.croscon.com. This package is not our internal package and is one we normally pull from PyPI. This critically errors and fails. Going back to pip 8 fixed this.
What I've run:
(.env) hayden@beard-machine ~/g/zvm-demo> pip --version
pip 9.0.1 from /home/hayden/gits/zvm-demo/.env/lib/python3.5/site-packages (python 3.5)
(.env) hayden@beard-machine ~/g/zvm-demo> pip install -r requirements.txt \
--extra-index-url http://pip.croscon.com:8088/simple/ \
--trusted-host pip.croscon.com
