How to clean up conflicting versions of wxpython?

[Isaac Ullah]

Dear all,

I've got a Xubuntu 12.04 machine that I use for development work on the
GRASS GIS project, which requires wxpython (version 2.8). I also do some
other python programming, and was recently experimenting with the latest
version of wxpython (3.0), which I compiled and installed from source
following these instruction s(http://www.wxpython.org/BUILD.html). However,
since I've done that, GRASS (and some other programs like OpenStereo) give
the following runtime error:

ERROR: wxGUI requires wxPython. libwx_gtk2u_core-3.0.so.0: cannot open
shared object file: No such file or directory

I tried to manually remove all the installed files, but I'm not sure if I
got them all because I can't find a log that tells me where everything went
when I did the install. I've also tried removing and reinstalling
python-wxgtk2.8 with the package manger, but my system seems still to be
"stuck" thinking that there is the 3.0 version installed (even though I can
confirm that 2.8 installs in the correct place).

So, can anyone here help me to find out why programs are still looking for
the 3.0 version of the libraries? It's a pretty major problem for me,
because I need to use this particular computer for development. Any help
will be greatly appreciated!

Sincerely,

Isaac Ullah

PS. Please let me know if there are any files, output of commands, or
additional information that could aid in debugging this problem, and I will
be happy to provide them

I suspect you'd find more people knowledgeable about this on wxPython
mailing list.

I think you have some left over Python modules that you need to clean
up. Check all the directories of Python sys.path on your system for them.

Try something along the lines of the following in your top level file:

import wxversion
wxversion.select('2.4')
import wx

Or additional build options can also be selected, although they will not
be required if they are not installed, like this:

import wxversion
wxversion.select('2.5.3-unicode')
import wx

Or you can require an exact match on the build options like this:

import wxversion
wxversion.select('2.5.3-unicode', optionsRequired=True)
import wx

Finally you can also specify a collection of versions that are allowed
by your application, like this:

import wxversion
wxversion.select(['2.5.4', '2.5.5', '2.6'])
import wx

Dear Vadim,

Your advice...

...worked brilliantly! I saw that sys.path[9] was'/usr/local/lib/python2.7/dist-packages/wx-3.0-gtk2'. This allowed me to track down some lingering wx3.0 files in
/usr/local/lib/python2.7/dist-packages/, including a wx.pth file that still
pointed to wx-3.0-gtk2. I deleted the lingering files, and changed the
value in that wx.pth file to wx-2.8-gtk2-unicode, and now everything works
as it did (GRASS and OpenStereo both open correctly)!

Thanks also to Gadget Steve for the extra info!

Cheers,

~Isaac

Isaac,

If you find or write a small, simple python script that uses wxPython
and then run it with the -v flag it will tell you exactly what is going
on. e.g.:

$ python -v -c "import wx; print 'Done';"

On my system gives:

import zipimport # builtin

# /usr/lib/python2.7/site.pyc matches /usr/lib/python2.7/site.py
