Running virtualenv myvenv --python=python fails with "The executable python (from --python=python) does not exist" even if python is on the PATH:

$ which python
/c/Python27/python

The issue is wrong executable detection on Windows. python is equivalent to python.exe on Windows but this is not recognized by virtualenv. It works only if you use virtualenv myvenv --python=python.exe.

FYI, it works if you do virtualenv --python=3.4 myenv or virtualenv --python=2.7 myenv.

Also works with --python=2 or --python=3

I see little point in the user supplying --python=python as that's (in effect) the default. And --python-C:\Python34\python seems odd - why not just add the .exe? That's not to say this isn't somewhat odd behaviour, I'm just not sure it's a major issue in practice.

Looking at sashahart/vex#11 I'm not clear if you are saying there that vex passes --python=python or you did so. If the former, it probably shouldn't, and I'd say that's a bug in vex. If the latter then I'd class this as user error (you should have omitted the --python argument).
