Virtualenv: Can't create a python 2.7 environment
Issue
In an Ubuntu 18.04 docker environment, tox is trying to do virtualenv --no-download --python /usr/bin/python2.7 py27. With virtualenv 20.0.10 this worked. As of 20.0.11, this fails with an error:
TypeError: unsupported operand type(s) for /: 'tuple' and 'str'
It should still work.
Environment
Provide at least:

The specific error looks like it was introduced in #1728 at https://github.com/pypa/virtualenv/blob/master/src/virtualenv/create/via_global_ref/builtin/python2/python2.py#L79-L85. Specifically, this line (https://github.com/pypa/virtualenv/blob/master/src/virtualenv/create/via_global_ref/builtin/python2/python2.py#L85)
return mappings[0] / name, mappings[1], False
should probably be
return mappings[0][0] / name, mappings[0][1], False
since mappings are a list of tuples.

FWIW, I'm seeing this with unicode instead of str:
