I'm trying to configure a Django test application for a personal project.
I have previous Django experience, but that was all with Python 2.7.x.
I'd like to start using 3.x when possible, and this project seems like a
good way to start.
Backend is a standard Postgres 9.4 installation, Apache 2.4, a
virtualenvwrapper pointing to the Python 3.4 executable, operating system
is OSX 10.10. mod_wsgi and mod_wsgi3 have both been installed via homebrew.
However, there are issues getting mod_wsgi and mod_wsgi3 to work with
python 3. Specifically, `./manage.py runserver 8080` works fine, but when
I try to use a virtualhost configuration with Apache, I get
mod_wsgi (pid=29906): Target WSGI script
'/Users/jason/projects/geocode_django/geodjango/geodjango/wsgi.py' cannot
be loaded as Python module.
mod_wsgi (pid=29906): Exception occurred processing WSGI script
'/Users/jason/projects/geocode_django/geodjango/geodjango/wsgi.py'.

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
and virtualhost file is:

My issue is that if I have a python 2.7 virtualenv with the same
virtualhost with the LoadModule pointing to
LoadModule wsgi_module
/usr/local/Cellar/mod_wsgi/4.4.7/libexec/mod_wsgi.so
and replace
with open("/Users/jason/.virtualenvs/geodev_env3/bin/activate_this.py")
as f:
code = compile(f.read(),
"/Users/jason/.virtualenvs/geodev_env3/bin/activate_this.py", "exec")
exec(code,
dict(__file__="/Users/jason/.virtualenvs/geodev_env3/bin/activate_this.py"))
in wsgi.py with
exec(open("/Users/jasonjohns/.virtualenvs/geocode_env/bin/activate_this.py").read())
I can load up the site with the URL `dev.geocode.com`. Otherwise, I get an
error 500 page with the error output in the log file.
I originally thought this was an issue with psycopg2, and filed a [bug
report][1]. However, the dev closed the issue as being concerned with
mod_wsgi, not psycopg.

Is there a solution for OSX virtualenvwrappers to use Python 3 with
mod_wsgi & apache?
