Push rejected, failed to compile Python app in heroku (Python Crash Course)

I am working through the learning log project in Python Crash Course by Eric Matthes, specifically working on the learning log app. I am trying to deploy to heroku but get this error:

(ll_env) C:\Users\benpg\Documents\Coding\Python\learning_log>git push heroku master

error: failed to push some refs to 'https://git.heroku.com/pacific-refuge-12657.git'

Tried everything here including the two other questions linked at the start, no luck.

Here's my requirements.txt:

Django==1.8.4
dj-database-url==0.3.0
dj-static==0.0.6
django-bootstrap3==6.2.2
gunicorn==19.3.0
static3==0.6.1
psycopg2>=2.6.1

Edit: I am using django 2.2.4. My requirements.txt is the way it is because there is a note in the book saying 'if you're using Windows, make sure your version of requirements.txt matches the list shown here regardless of which packages you were able to install'. Why is this?

This is the first requirements.txt I had, autogenerated except for the last line. This one didn't work either, same error message:

dj-database-url==0.5.0
dj-static==0.0.6
Django==2.2.4
django-bootstrap3==11.1.0
gunicorn==19.9.0
pytz==2019.2
sqlparse==0.3.0
static3==0.7.0
psycopg2>=2.6.1

Just had the same issue, changing the Python version back do 3.7.3 fixed it. Was able to build python and execute.
