ImportError: No module named trac

[Fernando N Filho]

Hello there,

I recently tried to upgrade my Trac Version from 0.11 to 0.12. But I now receive the following error on http://trac.potterish.com/:

Mod_python error: "PythonHandler trac.web.modpython_frontend"

Traceback (most recent call last):

  File "/usr/lib64/python2.4/site-packages/mod_python/apache.py", line 287, in HandlerDispatch
    log=debug)

  File "/usr/lib64/python2.4/site-packages/mod_python/apache.py", line 461, in import_module
    f, p, d = imp.find_module(parts[i], path)

ImportError: No module named trac

My .htaccess is configured the following way:

SetHandler mod_python

PythonInterpreter main_interpreter

PythonHandler trac.web.modpython_frontend

PythonOption PYTHON_EGG_CACHE /var/www/vhosts/potterish.com/subdomains/trac/httpdocs/editores/db

PythonOption TracEnvParentDir /var/www/vhosts/potterish.com/subdomains/trac/httpdocs

PythonOption TracUriRoot /

PythonDebug on

I looked on the Trac website and saw this had something to do with the Apache Path, but don't know how to fix it, does anybody have an idea of whats going on?

Thanks!

1) mod_python is a deprecated deployment option. The project has been
mothballed by its creators in favor of mod_wsgi. You should really
switch to a new deployment option (probably mod_wsgi).

2) You probably need a PythonPath in there which indicates where the
Trac code is installed.

PythonPath "['/path/to/site-packages'] + sys.path"

It isn't really true to say that mod_python was mothballed in favour
of mod_wsgi. The mod_wsgi package is certainly an alternative, but
mod_python was mothballed because no one was interested in working on
mod_python. :-)

I go with the simplified version so people don't ask the next question
of "What do I use instead?" ;-) Beats trying to explain the advantages
of mod_wsgi vs. FCGI in its various flavors.

Thanks for the help!

Things are working correctly now!
