Hi,
i've encountered a strange problem. When I install packages on the server in a
virtualenv
with pip manually, my page loads correctly.
If I install the requirements via "pip install -r requirements", then i get the
following error in apache:
Internal Server Error
Apaches error.log:

The inventory.wsgi file:
=====================================
import sys
import os
apache_dir = os.path.dirname(os.path.abspath(__file__))
project_dir = os.path.normpath(os.path.join(apache_dir + '/../..'))
app_dir = os.path.normpath(os.path.join(apache_dir + '/..'))
sys.path = [
os.path.join(project_dir, 'lib/python2.7/site-packages'),
project_dir,
app_dir
] + sys.path
os.environ['DJANGO_SETTINGS_MODULE'] = 'inventory.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
=====================================
There is nothing wrong with apache/nginx/memcached as other projects run
correctly.
Although I have a solution, I'm puzzled as to what causes this.
My requirements file:
-e svn+http://code.djangoproject.com/svn/django/trunk#egg=django
Werkzeug==0.6.2
-e git+git://kwebvs02/projects/common_utils#egg=common_utils
distribute==0.6.14
django-extensions==0.6
psycopg2==2.4.2
python-memcached==1.47
wsgiref==0.1.2
I use Django from trunk, common_utils is a local lib I developed .
So using above requirements, installation with pip -r fails, installing them
manually works, for instance
pip install psycopg2
Any idea?
Cheers,
Benedict
