This looks like a corrupt/mismatched existing virtualenv tox is
trying to reuse: https://github.com/pypa/virtualenv/issues/1213

You might try forcing tox to recreate the virtualenv from scratch
with the -r option like `tox -r -e docs` and see if it gets any
farther.

No more luck.
I am afraid that such pain is not going to motivate anyone to write documentation.
Is there any simpler way to check how a page would look before commiting it in Gerrrit ?
