pip3 10.0.0 installs a pip binary causing conflicts with python2

See original GitHub issue

Pip version: 10.0.0
Python version: 3.6.5
Operating system: macOS 10.13.4 (17E199)

Description:

When you upgrade pip3 from 9.0.3 to 10.0.0 pip3 installs an additional pip binary. This causes a conflict with coexistence of Python 2.7.x installations; contrary to the Python project’s intentions. From the Python project’s README file:

Python 3 and Python 2 Co-existence

Python.org Python 3.6 and 2.7.x versions can both be installed on your system and will not conflict. Command names for Python 3 contain a 3 in them, python3 (or python3.6), idle3 (or idle3.6), pip3 (or pip3.6), etc. Python 2.7 command names contain a 2 or no digit: python2 (or python2.7 or python), idle2 (or idle2.7 or idle), etc.

The release notes for Python2.7.14 have a similarly worded note on Python 3 and Python 2 co-existence.

For additional reference see: https://bugs.python.org/issue33290

I’m hesitant to add even more special casing for pip here, especially one that I think is just going to shift some of the confusion around and make some cases better and some worse. This is realistically a special case of the issues described in https://github.com/pypa/pip/issues/3164, so I’m going to close this in favor of further discussion over there.
