The =E2=80=98docutils=E2=80=99 distribution is declared (in setup.py) as a

Perhaps your build tool is incorrectly ignoring the setup_requires
parameter when invoking Setuptools?

I am seeing the same error on Python 3.6.1 on centos 7. My pip version is 10.0.1, so only the previous version of pip, released in April 2018 (see: https://pypi.org/project/pip/#history).

From some light googling I see that "setup_requires" isn't used by pip? https://github.com/pytest-dev/pytest-xdist/issues/136

That seems accurate.

In that case, I am closing this issue. The problem is with the
installation tool failing to honour the declared dependencies.

A work-around for this, until the bug in Pip is resolved, is to use a
different installation tool (or some wrapper around Pip, or some
preceding step) that will correctly install the declared dependencies
for building the package.

Metadata Update from @bignose:

I see where you're coming from. But pip is the recommended tool for installing python packages (see https://packaging.python.org/) and as such a lot of people who rely on your package are going to run into this problem.

Would you consider changing the "setup_require" to a hard requirement? i.e. include it in here https://pagure.io/python-daemon/blob/master/f/setup.py#_71

It looks like even in the setup.py there's a workaround for setuptools, where the requirement is added to "install_requires": https://pagure.io/python-daemon/blob/master/f/setup.py#_95-98

Making this change, while not ideal, will prevent a lot of headaches for users of libraries that depend on python-daemon.

I proposed a PR with my above suggestion here: https://pagure.io/python-daemon/pull-request/20

Apologies for commenting on a closed issue, but PEP 518 aims to replace setup_requires and has been implemented in pip for quite some time now: https://github.com/pypa/pip/pull/4144

Adding an additional file is probably a lot easier than fiddling with setup.py IMO ☺: https://www.python.org/dev/peps/pep-0518/#build-system-table
