unable to run wxPython on Lion

[Alex Hall]

Hi all,

I am trying to run a program using wxPython on Lion. I get a strange traceback:

Alexs-Mac-mini:bookshare mehgcap$ python dbc.py

Traceback (most recent call last):

If anyone can tell me what is going on and how to fix this, I would really appreciate it. This is Lion, 10.7.1, with Python 2.7 and wxPython 2.8.

Have a great day,

Hi Alex,

Are you using a 32-bit Python or have you set it to prefer / load 32-bit extensions? Otherwise, you'll run into a problem because wxPython 2.8 is 32-bit only.

Regards,

Kevin

I could be wrong, but I think there was only one installer for mac.
How do I set it to 32-bit mode? I found a forum post talking about
writing a preference, but the mac says that the command is not found.

Hi Alex,

There are two installers on python.org for Mac, if that is where you got it from.

Thanks,

Kevin

Alright, I'll uninstall this one and make sure I find the 32-bit
installer then. Thanks.

If you want or need to keep the 64-bit version of Python for some reason
then starting with 2.7 it includes a "python-32" command that you can
run instead of "python" that will force it to run in 32-bit mode.

I don't really need 64 bit, but is there a way to always use 32-bit
mode so I don't have to re-install python and all my third-party
packages? By the way, sorry for top-posting, this website (gMail
mobile) won't let me do an in-line reply.

If you have a python-32 binary then you can use that. Otherwise I'm not
sure if the old environment variable or system preferences tricks still
work with 2.7 and/or on Lion...

That's okay, I just installed 32 bit. I thought there was only one
because the site has a file for 10.6+ and one for up to 10.6, and the
10.6+ file says 36-64 bit so I thought it would be fine. I now have to
older one and my app runs... well, it runs, but with delays of a
minute or so and much locking up, but that's another thread.
