Running tox configured to use Python 3.3 using the py.test integration detailed at http://testrun.org/tox/latest/example/pytest.html, I get:

fix issue140: depend on virtualenv>=1.11.1

→ <<cset 9dce275b9bbd>>

It looks like this is no longer happening since virtualenv 1.11.1 was released.

Just an update on this. If tox has been installed and run with Python 3.3 on the same folder then it will subsequently behave itself.

@hpk42 Hi Holger, I'm getting the same error. The tox.ini is in my gviz-data-table repo, nothing fancy. Tripped over the error yesterday when I reinstalled a project I'd messed up.

Can you post the content of you tox.ini and the full output of tox -r -v -e py33?
