ATTENTION  ATTENTION  Imperfect answer ahead  To get the  latest memo  on the state of packaging in the Python universe  read this fairly detailed essay   I have just ran into this problem when trying to build install ansible  The problem seems to be that distutils really doesn t support install requires  Setuptools should monkey-patch distutils on-the-fly  but it doesn t  probably because the last release of setuptools is 0 6c11 from 2009  whereas distutils is a core Python project   So even after manually installing the setuptools-0 6c11-py2 7 egg running setup py only picks up distutils dist py  and not the one from site-packages setuptools    Also the setuptools documentation hints to using ez setup and not distutils   However  setuptools is itself provided by distribute nowadays  and that flavor of setup   supports install requires

I ve now seen this in legacy tools using Python2 7  where a build  like a Dockerfile  installs an unpinned dependancy  for example pytest  PyTest has dropped Python 2 7 support  so you may need to specify version  lt  the new package release    Or bite the bullet and convert that app to Python 3 if that is viable

This is a warning from distutils  and is a sign that you do not have setuptools installed  Installing it from http   pypi python org pypi setuptools will remove the warning

In conclusion   distutils doesn t support install requires or entry points  setuptools does   change from distutils core import setup in setup py to from setuptools import setup or refactor your setup py to use only distutils features   I came here because I hadn t realized entry points was only a setuptools feature    If you are here wanting to convert setuptools to distutils like me    remove install requires from setup py and just use requirements txt with pip change entry points to scripts  doc  and refactor any modules relying on entry points to be full scripts with shebangs and an entry point

As far as I can tell  this is a bug in setuptools where it isn t removing the setuptools specific options before calling up to the base class in the standard library  https   bitbucket org pypa setuptools issue 29 avoid-userwarnings-emitted-when-calling  If you have an unconditional import setuptools in your setup py  as you should if using the setuptools specific options   then the fact the script isn t failing with ImportError indicates that setuptools is properly installed   You can silence the warning as follows   python -W ignore  UserWarning distutils dist setup py  lt any-other-args gt    Only do this if you use the unconditional import that will fail completely if setuptools isn t installed      I m seeing this same behaviour in a checkout from the post-merger setuptools repo  which is why I m confident it s a setuptools bug rather than a system config problem  I expect pre-merge distribute would have the same problem

python setup py uses distutils which doesn t support install requires  setuptools does  also distribute  its successor   and pip  which uses either  do  But you actually have to use them  I e  call setuptools through the easy install command or pip install    Another way is to import setup from setuptools in your setup py  but this not standard and makes everybody wanting to use your package have to have setuptools installed

This was the first result on my google search  but had no answer  I found that upgrading setuptools resolved the issue for me  and pip for good measure   pip install --upgrade pip pip install --upgrade setuptools   Hope this helps the next person to find this link

I m on a Mac with python 2 7 11  I have been toying with creating extremely simple and straightforward projects  where my only requirement is that I can run python setup py install  and have setup py use the setup command  ideally from distutils  There are literally no other imports or code aside from the kwargs to setup   other than what I note here   I get the error when the imports for my setup py file are   from distutils core import setup   When I use this  I get warnings such as      usr local Cellar python 2 7 11 Frameworks Python framework Versions 2 7 lib python2 7 distutils dist py 267  UserWarning  Unknown distribution option   entry points      warnings warn msg    If I change the imports  and nothing else  to the following   from distutils core import setup import setuptools    noqa   The warnings go away   Note that I am not using setuptools  just importing it changes the behavior such that it no longer emits the warnings  For me  this is the cause of a truly baffling difference where some projects I m using give those warnings  and some others do not   Clearly  some form of monkey-patching is going on  and it is affected by whether or not that import is done  This probably isn t the situation for everyone researching this problem  but for the narrow environment in which I m working  this is the answer I was looking for     This is consistent with the other  community  comment  which says that distutils should monkeypatch setuptools  and that they had the problem when installing Ansible  Ansible appears to have tried to allow installs without having setuptools in the past  and then went back on that   https   github com ansible ansible blob devel setup py  A lot of stuff is up in the air    but if you re looking for a simple answer for a simple project  you should probably just import setuptools
