uWSGI + Django + Virtualenv unable to pick up _functools (import error)

Question

OK, So I have tried this with & without a virtualenv:

uwsgi --home /home/auston/new_proj/ --socket /tmp/uwsgi2.sock --chmod-socket --module app_wsgi --pp /home/auston/new_proj/nikeshere --logto /tmp/uwsgi.log --master --processes 4 -P

Pretty much no matter what, I get this:

    from _functools import partial, reduce
ImportError: No module named _functools

If I change --home to /usr/local/lib/python/2.6 I get fail on my app_wsgi.py import of os. Here it is, below, just in case:

import sys
import os

sys.path.append(os.path.abspath(os.path.dirname(__file__)))

import django.core.handlers.wsgi

application = django.core.handlers.wsgi.WSGIHandler()

Essentially I am asking, how can I get uWSGI to recognize functools OR get on the right path (path is in output above). I would appreciate any help you guys can give!!

P.S. Ubuntu 10.04 - uWSGI 0.9.6.5 - NGINX 0.8.53 - virtual env Python 2.6.5 - "regular (or system)" Python 2.6.6 - Django 1.2.3

UPDATE:

I was able to get uwsgi to start accepting requests if I omit the "--module" like so:

uwsgi --home /home/auston/new_proj --socket /tmp/uwsgi2.sock --chmod-socket --pp /home/auston/new_proj/nikeshere --logto /tmp/uwsgi.log --master --processes 4 -P

but now I get a app not found error:

"uWSGI Error wsgi application not found"

I'm closer but I would still appreciate suggestions as the app is not found because i cannot include the module needed to load it!

Answer 1

Why are you adding the -P option ? (the profiler)

Answer 2

Check out http://blog.zacharyvoase.com/2010/03/05/django-uwsgi-nginx/. He's using very similar set up.

Answer 3

So as noted above, the problem has been with the pythonpath & it's inability to find a module named _functools.

Apparently, _functools is a c module & I needed to append the it's path to the pythonpath in order for it to be found, so the difference from the original wsgi.py, is now:

import sys
sys.path.append('/usr/local/lib/python2.6/lib-dynload') # to load _functools
sys.path.append('/usr/local/lib/python2.6/site-packages') # to load django
sys.path.append('/usr/local/lib/python2.6/dist-packages') # cautionary to load django
sys.path.append('/usr/lib/python2.6') # to load os
import os

os.environ['DJANGO_SETTINGS_MODULE'] = 'iwin.settings'

import django.core.handlers.wsgi

application = django.core.handlers.wsgi.WSGIHandler()

Very hacky, but it works for now...
