[Pytest-commit] Issue #326: OSError 'Not a directory' when creating env on Jython 2.7.0 (hpk42/tox)

New issue 326: OSError 'Not a directory' when creating env on Jython 2.7.0
https://bitbucket.org/hpk42/tox/issues/326/oserror-not-a-directory-when-creating-env

Cosimo Lupo:

Hi,

I cannot use tox with Jython. I'm using the latest tox 2.3.1, and Jython 2.7.0 on OS X 10.10.5 with Java 1.7.0_79.

I tried to clone this repository and run the test suite using jython. Below is the output from test_venv.py::test_create that shows my issue.

It seems that the subprocess call to `virtualenv` command that creates the new tox environment is failing because a `listdir` call in `session._initlogpath` raises `OSError` because the `envlogdir` (where the output from the subprocess is to be logged) does not exist. If I browse the `.tox` directory in Finder, I can see there is no `{envdir}/log` subfolder. 

Thank you for your support.

Cosimo
