Error: Setting up a new project with virtualenv

Hello, I try to set up a new Project with a virtualenv with Django 1.7 and Python 3.4.

I get an error when I try to call the site. Maybe one of you knows the problem.

Here the error.log

2014-12-31 14:03:04,631 :Internal Server Error: / Traceback (most recent call last): File "/home/Wanderwichtl/.virtualenvs/django17/lib/python3.4/site-packages/django/core/urlresolvers.py", line 364, in urlconf_module return self._urlconf_module AttributeError: 'RegexURLResolver' object has no attribute '_urlconf_module'

# +++++++++++ VIRTUALENV +++++++++++
# If you're using a virtualenv, you should activate it at the top of your
# wsgi file, using code like this:
#
activate_this_path = '/home/Wanderwichtl/.virtualenvs/django17/bin/activate_this.py'
with open(activate_this_path) as f:
    code = compile(f.read(), activate_this_path, 'exec')
    exec(code, dict(__file__=activate_this_path))



# +++++++++++ CUSTOM WSGI +++++++++++
# If you have a WSGI file that you want to serve using PythonAnywhere, perhaps
# in your home directory under version control, then use something like this:
#
#import os
#import sys
#
#path = '/home/Wanderwichtl/WeingutBender/weingutBender'
#if path not in sys.path:
#    sys.path.append(path)

#from my_wsgi_file import application


# +++++++++++ DJANGO +++++++++++
# To use your own django app use code like this:
import os
import sys
#
## assuming your django settings file is at '/home/Wanderwichtl/mysite/settings.py'
path = '/home/Wanderwichtl/WeingutBender/weingutBender'
if path not in sys.path:
    sys.path.append(path)

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

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


# +++++++++++ FLASK +++++++++++
# Here is a simple Flask app. It is currently serving the default welcome
# page.  You can adapt this if you want.
#
# If you're using a different web framework, you'll need to comment all of this
# out

#from flask import Flask

#application = Flask(__name__)

#@application.route('/')
#def hello_world():
#    return """
#            <html>
#            <head>
#                <title>Python Anywhere hosted web application</title>
#            </head>

#            <h1>Hello, World!</h1>
#            <p>

Thanks for the awesome post, you gave exactly the right information to help you debug :-)

I think this is a Django version problem; the commented-out code in the WSGI file that you uncommented to get it working with Django and a virtualenv is for Django 1.3. For 1.7 you need to replace this:

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

with this:

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

I think we should update the template WSGI file, as you're not the first person to be tripped up by this.

Hi gang, brief update, we've just released a new way to handle virtualenvs which should avoid the system-site-packages / shadowing issues. There's an overview here and a guide switching across from the old system here.

We've also updated the default manual-config wsgi file so it has correct instructions re: that get_wsgi_application() call...
