Setuptools: requires-python is incompatible with the pythonversion in use

[ailjushkin]

Can anybody explain why does that happen?

Version of pip

pip -V
pip 9.0.1 from c:\python27\lib\site-packages (python 2.7)

Error
Error while installing my package:

pip install mypackage -v -v -v

(requires-python:==2.7.*, ==3.6.*) is incompatible with the pythonversion in use. Acceptable python versions are:==2.7.*, ==3.6.*

Python version

python --version
Python 2.7.14 (v2.7.14:84471935ed, Sep 16 2017, 20:19:30) [MSC v.1500 32 bit (Intel)] on win32

Setuptools version

That requires-python requires the Python to be both equal to 2.7.x and equal to 3.6.x. You'll be hard-pressed to find a Python version that satisfies that requirement ;).

The syntax I've seen used is: >=2.7.*, !=3.0.*, !=3.1.*, ..., !=3.5.*.

@jaraco Awesome, thank you very much indeed.
