Originally reported to Sphinx as sphinx-doc/sphinx#9825, investigating that issue revealed that tox is installing docutils==0.18 whereas Sphinx requires <0.18.

First, grab jaraco/pytest-checkdocs@b4153a4 (the head has a workaround) and run tox -e docs.

$ git clone https://github.com/jaraco/pytest-checkdocs
$ cd pytest-checkdocs
$ git checkout b4153a403388c4944c5a4f883b68bfa5531b1617
$ tox -e docs

It fails because the wrong version of docutils is installed.

docutils is required both by the project and by sphinx via the extras installed for the environment. You can see in the other report that if I create the virtualenv and install the packages directly using the same commands used by tox, pip is able to install the required version without any conflicts. However, if I run with tox, it uses the legacy resolver and reports a conflict:

  congratulations :)

I took a peek at the tox code but didn't see anything that would indicate that it's configuring the legacy resolver.

Do you have any clue as to why tox causes conflicting requirements to be installed, but when I run the commands, they work as expected?

You configure tox to use the legacy resolver explicitly with https://github.com/jaraco/pytest-checkdocs/blob/b4153a403388c4944c5a4f883b68bfa5531b1617/tox.ini#L15-L17

Well dang. Now I feel dumb. I'd considered that possibility, but failed to check. Thanks for finding that!
