New issue 155: ERROR: InvocationError: could not find executable 'virtualenv'
https://bitbucket.org/hpk42/tox/issue/155/error-invocationerror-could-not-find

Chris Withers:

So, this is using Python 3.3.0 on Windows 7.

I see this:

<tools path>\Scripts\python.exe -c "import pip; pip.main();" install --upgrade tox

...gives:

Requirement already up-to-date: tox in <tools path>\lib\site-packages
Requirement already up-to-date: virtualenv>=1.11.2 in <tools path>\lib\site-packages (from tox)
Requirement already up-to-date: py>=1.4.17 in <tools path>\lib\site-packages (from tox)

Looking at versions:

Python 3.3.0 (v3.3.0:bd8afb90ebf2, Sep 29 2012, 10:55:48) [MSC v.1600 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import tox
>>> tox.__version__
'1.7.0'
>>> import py
>>> py.__version__
'1.4.20'
>>> import virtualenv
>>> virtualenv.__version__
'1.11.4'

When I attempt to do:

<tool path>\Scripts\python.exe -c "import tox; tox.cmdline();" -
c tox.ini -v
using tox.ini: <workspace>\tox.ini
using tox-1.7.0 from <tools path>\lib\site-packages\tox\__init__.py
py26 create: <workspace>\.tox\py26
ERROR: InvocationError: could not find executable 'virtualenv'

Stepping through _venv.VirtualEnv.getcommandpath suggests that py.path.local.sysfind is being called with:

(Pdb) self.envconfig.envbindir
local('<workspace>\\.tox\\py26\\Scripts')

...rather than the local('<tools>\\Scripts') I would expect.

This is the call to create .tox\py26, so its scripts will not exist yet.

The tox.ini in question is here:
