It's deeply unclear to me what is happening -- I don't have a clue what all these "unknown" values are. Normally I'd assume that was a pip bug, but since virtualenv just underwent a substantial rewrite...

[xavfernandez]

It likely comes from your old pip 8.1.2 version that does not understand pyproject.toml (and therefore also the fact that it uses an old setuptools that does not understand setup.cfg).
Nevermind, virtualenv is installed from a wheel.

[alex]

I'm attempting to update pip before installing virtualenv with it, will report back on how that works.

[alex]

Upgrading pip seems to solve this. If that's considered sufficient, I'm happy to close this.

[gaborbernat]

Consider this duplicate of #1618

[gaborbernat]

@xavfernandez the zipp dependency is not installed from wheel, that's where the error comes from.
