I have set up a basic site in Django and am trying to serve it using Apache 2, however when trying i get an error:

My installed version are: Apache/2.4.29 (Ubuntu), mod_wsgi/4.5.17, Python/3.6, Django/2.2.10

My djangoproject.conf for apache2 is:

<VirtualHost *:80> 
 ServerAdmin admin@customspirit.co
 ServerName customspirit.co 
 DocumentRoot /home/ubuntu/Django

 <Directory /home/ubuntu/Django/custompspiritco>
  <Files wsgi.py>
   Require all granted
  </Files>
 </Directory>

</VirtualHost>

The init.py file where the error is looks like:

from django.utils.version import get_version

VERSION = (2, 2, 10, 'final', 0)

__version__ = get_version(VERSION)


def setup(set_prefix=True):
    """
    Configure the settings (this happens as a side effect of accessing the
    first setting), configure logging and populate the app registry.
    Set the thread-local urlresolvers script prefix if `set_prefix` is True.
    """
    from django.apps import apps
    from django.conf import settings
    from django.urls import set_script_prefix
    from django.utils.log import configure_logging

    configure_logging(settings.LOGGING_CONFIG, settings.LOGGING)
    if set_prefix:
        set_script_prefix(
            '/' if settings.FORCE_SCRIPT_NAME is None else settings.FORCE_SCRIPT_NAME
        )
    apps.populate(settings.INSTALLED_APPS)

The wgsi.py file looks like:

 import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'customspiritco.settings.production')

application = get_wsgi_application()

I get an Internal Server Error(500) every time i try and load anything and the error repeats in the log.

I have now reinstalled Django to version 2.2.14 which has solved the issue and brought a new issue

After compiling mod_wgsi for my version of python this error has now been replaced by:

  • are you sure get_version() is from django.utils.version? You're using Django 2.2, but I don't see django.utils having the version submodule in https://docs.djangoproject.com/en/2.2/ref/utils/ – ewokx Jul 07 '20 at 08:28
  • I can see the version.py file in the utils folder plus the Django server will run without Apache which seems to indicate that the contents of the _init_.py file are correct – AHopefulFool Jul 07 '20 at 08:35
  • Yeah, the documentation and the code don't seem to correspond properly. Is your mod_wsgi compiled against the right python version? (in this case python3.6)? perhaps https://stackoverflow.com/questions/6454564/target-wsgi-script-cannot-be-loaded-as-python-module might help you? – ewokx Jul 07 '20 at 08:54
  • This might also help: https://modwsgi.readthedocs.io/en/develop/user-guides/installation-issues.html – ewokx Jul 07 '20 at 08:58
  • is django installed in the /home/ubuntu/Django/env environment or is it in the general overall system env? – ewokx Jul 07 '20 at 09:07
  • After much trial and error I have found that I did have the wrong mod_wgsi, now I have compiled it for my Python I have been met with a new error above – AHopefulFool Jul 07 '20 at 10:39

After many hours of frustration it was all solved by creating a new virtual environment owned by the user ubuntu. Previously i must have made it using sudo and that had caused the issue of not finding the Django module
