Python 2.7.15 install fail

[welbo97]

Trying to install with pip2.7 on a Centos 6 machine. pip2.7 install -Iv https://github.com/Peter-Slump/python-keycloak-client/archive/v0.2.2.zip

Possibly a distutils version issue?

Returns error code 1 with:

    /usr/local/lib/python2.7/distutils/dist.py:267: UserWarning: Unknown distribution option: 'python_requires'
      warnings.warn(msg)

Hello @welbo97, please tell me which pip2.7 version you are using? This package requires pip version >=8.1.2, for supporting PEP 508 style environment markers.

[welbo97]

pip 19.0.3 from /usr/local/lib/python2.7/site-packages/pip (python 2.7)

The installation came from a package install with a requirement.txt file to load dependencies, including: python-keycloak-client == 0.2.2

[nkoshell]

Ok, your version setuptools must be >=20.2. For same reasons
