tox fails when using python < 3.6

[hpk42]

when trying to run tox -e py35 or in a direct pytest run on py35 i get these errors:

Thanks for reporting this.

tox has py36 env, not py35 (/juga0/pyac/blob/master/tox.ini#L2).

Though the error doesn't come from the python version, i'm not able to reproduce it. Are you running the last version from master?, which steps you followed to run it?

i am using ubuntu 16.04 as base system and do not have python3.6 there. i just went to a fresh checkout and typed "tox -e py35". It indeed seems you are using py36 features that .e.g you can pass "LocalPath" objects to os.stat(). What happens if you do "tox -e py35" on your machine?

tox -e py35
GLOB sdist-make: /tmp/pyac/setup.py
py35 create: /tmp/pyac/.tox/py35
ERROR: InterpreterNotFound: python3.5

You're right the bug come from the version, however if you just run tox then the error will be?

ERROR:   py36: InterpreterNotFound: python3.6

I'd prioritize to implement all functionality and only add support other versions if actually this is used. If you prefer to don't add artful to your sources.list and pin it nor have access to a vm or other machine, then i can change this.

I changed the code so it can also run with Python 3.5
It'd be great if you could test it again.
Thanks.
