RuntimeError: Python version >= 3.5 required

When installing in a virtual environment with Python 2, the setup fails with

    ERROR: Complete output from command python setup.py egg_info:

    RuntimeError: Python version >= 3.5 required.

It seems to be trying to install numpy-1.17.0rc1, which needs Python 3.

This happens even if trying to pip install -r from a file where a minor version of numpy is pinned (perhaps related with having numpy listed as a setup_requires apart from install_requires?)

Steps to reproduce:

mkvirtualenv test   # python 2
pip install --no-cache-dir reverse-geocoder

If anyone's interested, we've found a (hacky) workaround:

1. Manually install dependencies (numpy & scipy)
2. pip install --no-deps reverse-geocoder

I'm having the exact same issue. I'm using docker, and this issue is causing my docker build to break with requirements.txt.
@Laski workaround seems to work.
