I'm experimenting to publish my django project with Apache mod_wsgi. I created a simple django3 project named sampleapp in virtualenv. Then, I configured my /etc/apache2/sites-enabled/000-default.conf file as follows
<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot /var/www/html
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
WSGIDaemonProcess sampleapp python-home=/var/www/html/sampleapp/env python-path=/var/www/html/sampleapp:/var/www/html/sampleapp/env/lib/python3.7/site-packages
WSGIProcessGroup sampleapp
WSGIScriptAlias /sampleapp /var/www/html/sampleapp/sampleapp/wsgi.py process-group=sampleapp
</VirtualHost>
Although my virtualenv's python version is 3.7, mod_wsgi is used system's python version(3.5), so it doesn't see my virtualenv and doesn't use its python version. My apache error log as follows:

How do I configure mod_wsgi to use the python version of my venv? Or where is my fault? Thanks for the answers.
So the mod_wsgi is compiled to a specific version of Python for Apache. You cannot make it run a different version of python. You can either rebuild that mod_wsgi to the correct version, or change the virtual environment. This deletes virtualenv wrapper but keeps project files.
I think that "changing the virtualenv" would be easier.
rmvirtualenv env-name
mkvirtualenv -p python3.5 env-name
setvirtualenvproject env-name
When you use 'mkvirtualenv' use the -r tag for a requirements.txt
Or rebuild the mod_wsgi:
