Setuptools needs to be vendored #9034
Description
Both jinja2 and pytest have a setuptools dependency, but we aren't currently vendoring setuptools:
$ grep -R pkg_resources
jinja2/loaders.py: from pkg_resources import DefaultProvider, ResourceManager, \
_pytest/vendored_packages/pluggy.py: from pkg_resources import (iter_entry_points, DistributionNotFound,
_pytest/config.py: import pkg_resources
_pytest/config.py: for entrypoint in pkg_resources.iter_entry_points('pytest11')
_pytest/assertion/rewrite.py: self._register_with_pkg_resources()
_pytest/assertion/rewrite.py: def _register_with_pkg_resources(cls):
_pytest/assertion/rewrite.py: import pkg_resources
_pytest/assertion/rewrite.py: pkg_resources.__name__
_pytest/assertion/rewrite.py: pkg_resources.register_loader_type(cls, pkg_resources.DefaultProvider)
_pytest/outcomes.py: from pkg_resources import parse_version as pv
_pytest/outcomes.py: "pkg_resources to parse version strings." % (modname,),Currently, when I build python with Spack and use it to try to run the unit tests, I see the following error message:
==> Error: No module named 'pkg_resources'
