Installation issue on Python 3.5.1 #40
Description
With pytest's CI I've noticed that it looks like the latest release causes problems on Python 3.5.1.
Initially:
$ tox
Traceback (most recent call last):
File "/home/travis/virtualenv/python3.5.1/bin/tox", line 7, in <module>
from tox import cmdline
File "/home/travis/virtualenv/python3.5.1/lib/python3.5/site-packages/tox/__init__.py", line 9, in <module>
import pluggy

from .manager import PluginManager, PluginValidationError

import zipp
ImportError: No module named 'zipp'
The command "tox" exited with 1.
With tox -vv: https://travis-ci.org/pytest-dev/pytest/jobs/647622826
Not sure if I'm missing something etc, and if this should be supported/pinned, but wanted to leave it here already.
pytest might just remove 3.5.1 from its CI after all.
