error with virtualenv and python 3.4a1

[dhellmann]

I'm having trouble getting virtualenv to work with python 3.4a1. It's entirely possible this has something to do with my setup, although I don't think I have anything unusual installed. It does work with 2.6-3.3.

Oh, one possible factor is that I'm running virtualenv from my user-directory:

hubert:tmp$ which virtualenv
/Users/dhellmann/Library/Python/2.7/bin/virtualenv

It also fails from tox, but I don't know if tox uses that same virtualenv executable or not.

I don't think it's just you. I have a similar setup and problem.

[macobo]

I can also reproduce, with identical stack trace.

[lparkes]

The problem is that virtualenv isn't copying over the "operator" module.

I am having this problem too on OS X 10.8.5

collections in 3.4 is a module and we're not recursively copying it.

[pnasrat]

Investigating.

[msabramo]

I will have a PR shortly...

[pnasrat]

Ah I just did the same, also pulling in all the 3.3 modules. I'll merge mine thanks for the PR though

[msabramo]

Cool, good to see it fixed!

[msabramo]

This should be marked resolved?
