Problems With Aptana Studio (and/or Python) under Lion

After installing Lion, Aptana has stopped working -- I can no longer run any Python开发者_运维问答 code, despite me failing to find any other problems with Python my system. I've tried restoring defaults in Aptana, re-installing and looking for any missing references in Aptana to python components.

Running a simple "hello world" .py script generates a console message:

Traceback (most recent call last):

Have you tried removing your interpreter and adding it again (that way PyDev would update your PYTHONPATH?

It seems like the problem is that the math.so is not compatible with the latest changes in Lion (so, maybe in the update for Lion it got to 2.7 and you're still with 2.6 in the PYTHONPATH configure in Eclipse?)

For me, a better choice would be using an interpreter downloaded from python.org (where you have more control and don't need to rely on what Mac gives you) and configure the python from python.org.
