Minimum, Complete, Verifiable Example

• CentOS Linux 7.5
• Python 2.7.5
• Centos 7 package: python-setuptools 0.9.8 (latest from Redhat 7, added Apr 12, 2017)

Create a setup.py with natsort required:

# -*- coding: utf-8 -*-
# !/usr/bin/python

import sys

from setuptools import setup

sys.path.insert(0, '.')

if __name__ == "__main__":
    package = "test_bug"
    setup(
        name=package,
        version="0.0.1",
        author="Nobody",
        author_email="nobody@aol.com",
        url="https://github.com/SethMMorton",
        license="ASLv2",
        packages=[package],
        package_dir={package: package},
        description=(
            'test'
        ),
        long_description=(
            'test'
        ),
        classifiers=[
            'Intended Audience :: System Administrators',
        ],
        data_files=[],
        install_requires=[
            'natsort'
        ]
    )

This can actually be resolved by

pip2.7 install --upgrade setuptools

on Centos 7. It's interesting to me Redhat offers no upgrade path for a modern python-setuptools.

I will close this issue.

What version of setuptools was being used?

@jondkelley FYI, natsort version 5.5.0 was just released with an update that supports older setuptools versions, so you shouldn't have to update to install natsort anymore.
