zipp package in dependency requires Python 3.6+

[Djailla]

Hello,

I'm facing an issue with the project django-macaddress especially with this PR :

django-macaddress/django-macaddress#39

I'm pushing to use tox-travis.
The configuration is pretty straight forward but the travis fails with Python 3.5 with this message :

https://travis-ci.org/github/django-macaddress/django-macaddress/builds/715081813

306The command "pip install tox-travis" failed and exited with 1 during .```

Any idea ?

Thanks

$ pip install tox-travis

zipp requires Python '>=3.6' but the running Python is 3.5.6
The command "pip install tox-travis" failed and exited with 1 during .

That PR was failing because some dependency of python setup.py install installs a new version of zipp that doesn't support Python 3.5.

And there's no need to run python setup.py install when testing via tox, it's done for you inside the virtualenv.

Please see PR Djailla/django-macaddress#1 to fix it.
