How do I get Phusion Passenger to recognize the correct version of Python for a web application?

I'm trying to set up my first Python web application through Flask. I've used the setup module on my hosting service, and I've hit a problem. When I try to run the app, I get an error page from Phusion Passenger. In the searching I've done so far, similar problems seem to come from Passenger's inability to locate the needed software. But I haven't done this before, so I may well be misunderstanding the problem. All help much appreciated.

Here are the contents of passenger_wsgi.py:

import imp
import os
import sys

sys.path.insert(0, os.path.dirname(__file__))

wsgi = imp.load_source('wsgi', 'flaskblog.py')
application = wsgi.application

And here is what the site admin pulled from the error log:

[ E 2020-05-25 15:09:08.9018 32404/T1q age/Cor/App/Implementation.cpp:221 ]:

The problem was that I hadn't activated the environment. (I was following instructions that didn't include that step.) I created the app using cPanel, and at the end of the process, cPanel provided a Terminal command (at the top of the page) to activate the app. I entered Terminal through cPanel, ran that command, then ran "pip install flask."

Then I restarted the application and reloaded the page. Now it works!
