[Python-modules-team] Bug#914387: python3-pip: cannot import name 'main' from 'pip'

[Alexander William Wong]

Package: python3-pip
Version: 9.0.1-2.3
Severity: important


Dear Maintainer,

I upgraded python3-pip and python3 today.

Running pip3, I see that the wrapper script is broken.
The wrapper script should import from main.__internal__ instead of main.

The paths for pip3 and python3 -m pip --version are the same.

=====
$ pip3
Traceback (most recent call last):
  File "/usr/bin/pip3", line 9, in <module>
    from pip import main
ImportError: cannot import name 'main' from 'pip' (/home/alexander/.local/lib/python3.7/site-packages/pip/__init__.py)

$ python3 -m pip --version
pip 18.1 from /home/alexander/.local/lib/python3.7/site-packages/pip (python 3.7)
