🐞 bug report

Affected Rule

The issue is caused by the rule: pip_import

Is this a regression?

No. Yes. Maybe.

Description

I'm trying to invoke the pip_install workspace rule with Python2, setting python_interpreter to "python2". But pip_install fails with the error /usr/bin/python2: No module named python.pip_install. I tracked this down to missing __init__.py files in the rules_python/python and rules_python/python/pip_install directories. Python2 must require init.py files in the whole module path whereas Python3 doesn't... Anyhow, once the files are there, python2 fails with the error:

  File "python/pip_install/extract_wheels/__init__.py", line 18
    def configure_reproducible_wheels() -> None:
                                        ^
SyntaxError: invalid syntax

Which tells me that that's Python3 syntax. :( Is Python2 not supported for pip_install?
