Can I use other python implementation via virtualenv/virtualenvwrapper?

After a while of searching (maybe it's not enough, but I don't think I'm making progress doing that), I haven't been able to find information about compatibility of other Python implementations in virtualenv/virtualenvwrapper. By "other implementation" I mean things like PyPy, IronPython, Cython, Jython...

for example, I can create a virtualenv for a different python version using the following code .

mkvirtualenv -p /usr/bin/python2.6 new_venv

but when I tried to create a virtualenv for PyPy by:

mkvirtualenv -p /usr/bin/pypy new_venv

system throws some error.

EDIT: I'm using virtualenvwrapper-win. it throws

Running virtualenv with interpreter C:\pypy2-v5.8.0-win32\pypy.exe
New pypy executable in C:\Users\fangming.zfm\Envs\test-123\bin\pypy.exe
Installing setuptools, pip, wheel...done.
system cannot find the path specified.
system cannot find the path specified.
system cannot find the path specified.

why we can't do this? is it because of lack of interest, or is it technically infeasible?

The problem is due to pypy.exe being located under the /bin/ directory -- and not the Scripts directory (like virtualenvwrapper-win expects).

There's an issue for it (https://github.com/davidmarble/virtualenvwrapper-win/issues/30) and it should be relatively simple to fix.

Works for me:

$ mktmpenv -p pypy

New pypy executable in /home/phd/.virtualenvs/tmp-b29122e40f353f03/bin/pypy

This is a temporary environment. It will be deleted when you run 'deactivate'

$ python --version

What exactly is your error?
