Module sre, line 168, in ? AttributeError: 'module' object has no attribute 'hexversion' *****
This seems to be deep in Python standard library.
Not that deep actually. sre.py line 168 is this: if sys.hexversion >= 0x02020000:
Since I don't actually use Zope 2.6, does anyone have an idea on where the problem may come from ?
You're using restricted mode (the rexec module) and this apparently doesn't provide sys.hexversion. This is a shallow bug; it's already fixed in Python 2.3 (CVS).
Does any of you use ZShell with Zope 2.6 ?
It works fine in 2.5.1 with Python 2.1.3, so something has changed somewhere which breaks it.
Probably those versions of Python didn't have the test for sys.hexversion; it's testing whether this is Python 2.2 or higher. A workaround would be to set sys.hexversion to 0x02020000 (or to 0 if you're not sure which Python version you're using) before importing sre for the first time. --Guido van Rossum (home page: http://www.python.org/~guido/)
