mod_wsgi error: ModuleNotFoundError: No module named 'django'

Question

I am trying to deploy a very basic Django application with Apache 2.4 on Ubuntu 18.04 without using a virtual environment. When wsgi.py executes, it cannot find django module.

I have tried setting sys.path in wsgi, various solutions that define different configuration settings for 000-default.conf. Changing ownership of the site-packages folder to www-data for Apache, but nothing seems to work. I could make it work using virtualenv but for a production server, I do not want to use virtualenv. I can import django in Python's command line without an issue.

Following is my sample.tst.conf, if have already activated it using a2ensite command.

<code>
<VirtualHost *:80>

    ServerName sample.tst
    ServerAdmin webmaster@sample.tst
    DocumentRoot /var/www/html

    <Directory /home/raza/projects/sample/sample>
        <Files wsgi.py>
            Require all granted
        </Files>
    </Directory>

    WSGIDaemonProcess sample python-path=/home/raza/projects/sample
    WSGIProcessGroup sample

    WSGIScriptAlias / /home/raza/projects/sample/sample/wsgi.py

    <Location />
    WSGIProcessGroup sample
    </Location>

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

</VirtualHost>

How can I fix this problem? I am struggling with this issue for more than a week.

I am a very experienced programmer but very new to Linux, python, and Apache platform, so I may be making some obvious mistake.

I get following error in Apache log file:

Looks like django is installed into python2 (which is used by your OS). python3 comes with pre-installed pip3 package installer. So use "sudo pip3 install django" command to install django into python3 environment. pip will only install the packages into python2.
