Ah, sorry, i was confused, installing from a wheel works. It's just installing from a local or remote sdist that fails.

Given that my setup.py implements the normal distutils-style argv handling, i was expecting things to work, but pip-18.1 appears to fail before it even tries to run setup.py, so the only thing i can think of is that the PKG-INFO file could be causing a problem? I've also tried building an sdist with the https://pypi.org/project/build/ project's --sdist option; this sdist fails to install with pip-18.1 in the same way.
