I’m not sure if there’s any interest in maintaining the pip.main() as a passthrough command execution wrapper, but that could potentially mitigate the pain of upgrading.

I think this would make an excellent issue to discuss the relative merits of doing that (or not doing it).

I’m seeing the same thing with pip 9.0.2 while running on the python:3.6 docker container

pip version: 9.0.2
python version: 3.6.4
operating system: docker/linux

I’ve been able to narrow it down to occurring when the requests library is imported before the pip library. Here’s an example:

docker-user:~# python
Python 3.6.4 (default, Mar 14 2018, 17:49:05)
[GCC 4.9.2] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import requests
>>> import pip
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.6/site-packages/pip/__init__.py", line 45, in <module>
    from pip.vcs import git, mercurial, subversion, bazaar  # noqa
  File "/usr/local/lib/python3.6/site-packages/pip/vcs/mercurial.py", line 9, in <module>
    from pip.download import path_to_url
  File "/usr/local/lib/python3.6/site-packages/pip/download.py", line 40, in <module>
    from pip._vendor import requests, six
  File "/usr/local/lib/python3.6/site-packages/pip/_vendor/requests/__init__.py", line 98, in <module>
    from . import packages
  File "/usr/local/lib/python3.6/site-packages/pip/_vendor/requests/packages.py", line 12, in <module>
    sys.modules['pip._vendor.requests.packages.' + mod] = sys.modules["pip._vendor." + mod]
KeyError: 'pip._vendor.urllib3.contrib'
>>> exit()
docker-user~# pip --version
pip 9.0.2 from /usr/local/lib/python3.6/site-packages (python 3.6)

The reverse works fine:

docker-user:~# python
Python 3.6.4 (default, Mar 14 2018, 17:49:05)
[GCC 4.9.2] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pip
>>> import requests
>>> print(pip)
<module 'pip' from '/usr/local/lib/python3.6/site-packages/pip/__init__.py'>
