You can't upgrade distribute with pip under Python 3. This is a known problem. https://github.com/pypa/pip/issues/650

I think the problem is that with someone recently forgot to put the parentheses (i.e. "except ValueError, e:" should be "except (ValueError, e):") and therefore this does not work anymore with python3.

No, the syntax under Python 3 is except ValueError as 3, but that doesn't work with Python 2.4 and Python 2.5 and we are still supporting them.

It should be easy to fix.

It isn't. The solution is to not try to upgrade distribute with pip under Python 3. Uninstall it and install it again instead. //Lennart

Wouldn't merging Vinay's distribute3 branch fix this?

I don't think we should stop using 2to3 until we drop support for 2.5, which we haven't done yet. The codebase is very brittle, so conservatism is appropriate. I think the new setuptools + distribute branch could be the right place to do this, but that's up to the setuptools maintainers. //Lennart
