I’m experiencing this issue as well on more recent Pythons (latest available Python 3.5 binary for macOS).

I can replicate the issue by simply invoking tox twice on any of my projects. For example, consider portend:

portend master $ tox -e py35

ERROR:   py35: InvocationError for command '/Users/jaraco/code/main/portend/.tox/py35/bin/python /Users/jaraco/code/main/portend/setup.py --name' (exited with code 1)

Upgrading pip and setuptools to the latest results in the same outcome.

The first run works fine, but the second run fails when tox invokes setup.py --name. Because the package declares a setup_requires argument, and because tox isn’t honoring the PEP-518 declaration for that build dependency, the setup.py invocation falls back to honoring setup_requires, invoking the deprecated easy_install which has only old TLS support as was included in the Python 3.5.4 build on macOS.

My instinct is that tox should not be invoking setup.py (anything) and if it needs the name of the local package, it should get it another way. I believe the importlib_metadata project would be the best place for that functionality, and in issue 27, I’ve captured the shortcoming of that library. That issue also links to a workaround I’ve implemented in pytest-checkdocs that works with the current releases of importlib_metadata.

Fixed by installing non mac os python 2.7 brew install python@2
