What is the path for Python in WSGIDaemonProcess?

Question

Python

Hello.
I install pgAdmin 4. There is an example conf-file in the manual.

<VirtualHost *>
    ServerName pgadmin.example.com

    WSGIDaemonProcess pgadmin processes=1 threads=25 python-home=/path/to/python/virtualenv
    WSGIScriptAlias / /opt/pgAdmin4/web/pgAdmin4.wsgi

    <Directory /opt/pgAdmin4/web>
        WSGIProcessGroup pgadmin
        WSGIApplicationGroup %{GLOBAL}
        Order deny,allow
        Allow from all
    </Directory>
</VirtualHost>

I don't understand the line WSGIDaemonProcess pgadmin processes=1 threads=25 python-home=/path/to/python/virtualenv
What is this "virtualenv" path? Where can you read about it?

If you only have pgadmin then you can use system python and remove python-home=/path/to/python/virtualenv . In fact, this is the path where all the necessary python libraries for this instance / virtual server are located. When several different projects work on the same server and use different sets of libraries, it is best to separate them through virtualenv. Each virtualenv can only contain the required libraries for a particular project.
