django和mod_wsgi配置错误

Question

I want config My Django Web Application on ubuntu Server but has error.

I Searched in StackOverflow but not occurred for any developer

this is wsgi.py

import os
import sys
sys.path.append('/var/www/Happ')
os.environ['DJANGO_SETTINGS_MODULE'] = 'Happ.settings'
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

this is /etc/apache2/sites-available/000-default.conf

    <VirtualHost *:80>

        WSGIDaemonProcess Happ python-path=/var/www/Happ:/var/www/Happ/env/lib/python2.7/site-packages
        WSGIProcessGroup Happ
        WSGIScriptAlias / /var/www/Happ/Happ/wsgi.py process-group=Happ

        Alias /media/ /var/www/Happ/media/
        Alias /static/ /var/www/Happ/static/

        <Directory /var/www/Happ/static>
        Require all granted
        </Directory>

        <Directory /var/www/Happ/media>
        Require all granted
        </Directory>

        <Directory /var/www/Happ/Happ>
        <Files wsgi.py>
        Require all granted
        </Files>
        </Directory>

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

</VirtualHost>

and finally error in ${APACHE_LOG_DIR}/error.log

Answer 1

It seems you've just hit the http://bugs.python.org/issue21306 bug. Can you try upgrading python to 2.7.7 or above?
