My guess is that somehow the server is not loading the correct
packages as C:\\Python\\lib\\site-packages\\pastedeploy-1.5.0-py2.6.egg
\\paste\\deploy\\loadwsgi.py is the path to my global python install.

Running from the virtual env paster works.
Running the wsgi handler also works.

Reinstalled the virtual env from scratch - still didn't work. This is
the basic hello world app for testing.

Another piece of info...may help: when I installed the first time
without a virtual environment i made another test app then configured
the environment then ran it from apache and it worked. After that only
failed attempts.
Any help...ideas would be appreciated.
I am running win 7 x64. virtualenv created with py 2.6.6.

[Jonathan Vanasco]

did you run `setup.py develop` ?

[Artur Daschevici]

Yes. Same outcome.

This is my handler.wsgi

import os, sys
from paste.deploy import loadapp
sys.path.append('h:/aaa/testsite')
#sys.path.append('g:/testsite/Lib/site-packages')
#import site
#site.addsitedir('/home/simplesite/env/lib/python2.5/site-packages')
#site.addsitedir('g:/testsite/Lib/site-packages')

os.environ['PYTHON_EGG_CACHE'] = 'h:/aaa/testsite/python-eggs'

#from paste.deploy import loadapp

application = loadapp('config:h:/aaa/testsite/development.ini')

Tried also adding the site-packages to path and without. No luck.

[Artur Daschevici]

Does anyone else have any other ideas...or any ideas on how to debug
this better?

At this point i would pretty much try anything new...well maybe short
of reinstalling everything from python up.

Have you tried with the activate_this.py script ?

Your .wsgi is a python script so you can run:
C:\\Python\\Scripts\\Python.exe handler.wsgi
If you have no traceback then it should work with mod_wsgi too.
Add some print statements for debuging. Like print sys.path or import testsite

I managed to get somwhere...at least to get something usable to go on.
Seems that i set up previous versions of pylons on apache and that was
what was breaking my software. The discrepancy between the libs in my
virtual env and the lisb in my python install.
