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

Question

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

Do you have your requirements.txt at project root at the same level of manage.py? Also check the spelling. — MD. Khairul Basar

Django 1.8.4 is years out of date, doesn't receive security updates. There is a mismatch between Django 1.8 which supports up to Python 3.5, and Heroku which supports Python 3.6 and 3.7 (both support Python 2 but you should avoid Python 2 for new projects. — Alasdair

I would avoid following a tutorial written for Django 1.8. Lots has changed since then so you'll hit problems like this. I'm not familiar with the python-crash-course book, so I don't know whether there's a newer version that uses a more up to date version of Django. The pcc repo appears to have a copy of the project updated for Django 2.0 which might help you. — Alasdair

@MD. Khairul Basar requirements is in the right directory, spelling checked — Ben Gutteridge

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