Hey!

I have a django project which I tried to port using apache2 (Apache itself works very well on my computer). I worked through this tutorial: https://www.digitalocean.com/community/tutorials/how-to-serve-django-applications-with-apache-and-mod_wsgi-on-ubuntu-14-04 without create the django project.

When I tried to run my project I got the following error:

Quote:

So obviously python 2.7 comes into play but my official interpreter is python 3.4:
Code:

  [1]   python2.7
  [2]   python3.4 *


and gcc 4.9.3. isn't installed either:

Code:

 [1] x86_64-gentoo-linux-gnu-5.3.0 *
 [2] x86_64-pc-linux-gnu-5.3.0 *


So what is calling python 2.7?

my /etc/apache2/vhosts.d/00_default_vhost.conf:

Code:

....

<VirtualHost *:80>
   ServerName localhost
   Include /etc/apache2/vhosts.d/default_vhost.include

   <IfModule mpm_peruser_module>
      ServerEnvironment apache apache
   </IfModule>

    ServerAlias /static /var/www/localhost/htdocs/django/stundenplan/static/
    <Directory /var/www/localhost/htdocs/django>
        Require all granted
    </Directory>

    <Directory /var/www/localhost/htdocs/django/stundenplan/stundenplan/>
        <Files wsgi.py>
            Require all granted
        </Files>
    </Directory>

    WSGIDaemonProcess stundenplan python-path=/var/www/localhost/htdocs/django/stundenplan:/usr/lib64/python3.4/site-packages
    WSGIProcessGroup stundenplan
    WSGIScriptAlias / /var/www/localhost/htdocs/django/stundenplan/stundenplan/wsgi.py

</VirtualHost>
</IfDefine>



and my wsgi.py:

Code:

"""
WSGI config for stundenplan project.

It exposes the WSGI callable as a module-level variable named ``application``.

For more information on this file, see
https://docs.djangoproject.com/en/1.8/howto/deployment/wsgi/
"""

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "stundenplan.settings")

application = get_wsgi_application()



equery uses www-apache/mod_wsgi showd up:
Code:


[ Legend : U - final flag setting for installation]
[        : I - package is installed with flag     ]
[ Colors : set, unset                             ]
 * Found these USE flags for www-apache/mod_wsgi-4.4.21:
 U I
 + + python_single_target_python2_7 : Build for Python 2.7 only
 - - python_single_target_python3_3 : Build for Python 3.3 only
 - - python_single_target_python3_4 : Build for Python 3.4 only
 + + python_targets_python2_7       : Build with Python 2.7
 - - python_targets_python3_3       : Build with Python 3.3
 + + python_targets_python3_4       : Build with Python 3.4


Is " python_single_target_python2_7" the failure? I can't remeber set this variable? where is it come from?

kind regards
