Hi,

Note, it is checking for _core.py.

No it isn't. Look at the error message:

It's looking for a module name _core_ (with a trailing underscore).
This is the binary extension (_core_.so on Linux). It should be in

The files listed in the backtrace are the Python files which were

always refers to the .py files even if .pyc or .pyo files are actually

Michael, please check your wxPython installation (Robin Dunn's answer
[1]). There's no reason why the statements below should fail

import wxversion
wxversion.select('2.8')
import wx

This finally worked.

I've been following all the wxpython install/uninstall instructions to no avail. I looked at Robin's email responses you forwarded to me, but didn't see this one some how. Thanks for bringing it to my attention. I'm glad you've had better luck with responses than I have. I've reported a couple of well-documented bugs with the Mac version. Eventually I got work-arounds or solutions for some of these, but it took several months. I just figured that the development team was overloaded.

The issue is that now wxpython is supposed to be installed in a different place on disk than it has been up through 2.8.7.1. The install routine will not install into this new location unless you manually remove all prior versions. Otherwise, it will install into the prior location completely correctly, but giving bogus errors when you run wxversion. Nor does the wxpython uninstall remove the old location. So there is a problem in the wxpython installation routine. I don't know if this also affects Windows or just the Mac. But it will affect everyone on Macs who upgrade.
