mod_wsgi isn't honoring WSGIPythonHome
apache, mod-wsgi, python
Solution
Your mod_wsgi is likely compiled against a different Python version than you are trying to force it to use. For example, you can not use mod_wsgi compiled against Python 2.4 with a virtual environment constructed using Python 2.6.
Validate what version of Python mod_wsgi was built for in the first place.
Problem
I'm trying to get WSGI to run with a virtualenv setup. I have the virtualenv all working right: ``` (virtualenv)dev:/var/www/app$ which python /var/www/virtualenv/bin/python (virtualenv)dev:/var/www/app$ python Python 2.6.1 (r261:67515, Dec 5 2008, 22:09:34) [GCC 4.1.2] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import importlib >>> ``` And in my httpd.conf, I have the following, as described here: ``` WSGIPythonHome /var/www/virtualenv WSGIPythonPath /var/www/virtualenv/lib/python2.6/site-packages ``` But when I try to load the app via apache, i get the following error: ``` [Wed Dec 28 12:28:15 2011] [error] [client 127.0.0.1] mod_wsgi (pid=15026): Exception occurred processing WSGI script '/var/www/app/wsgi.py'. [Wed Dec 28 12:28:15 2011] [error] [client 127.0.0.1] Traceback (most recent call last): [Wed Dec 28 12:28:15 2011] [error] [client 127.0.0.1] File "/var/www/app/wsgi.py", line 29, in <module> [Wed Dec 28 12:28:15 2011] [error] [client 127.0.0.1] import importlib [Wed Dec 28 12:28:15 2011] [error] [client 127.0.0.1] ImportError: No module named importlib ``` What am I missing? How do even debug this kind of problem?
