I am getting an application error while running my django app on heroku. Here are the results from heroku logs:

Please help! I am new to deploying projects using heroku.I really don't understand these logs, so if someone could point me in the right direction, I would be most grateful.

  • You almost certainly shouldn't be using that --python-path parameter. Commented Apr 8, 2017 at 18:18
  • Now it says Failed to find application: 'expense_manager' @DanielRoseman Commented Apr 8, 2017 at 18:30
  • What does your file tree look like? stackoverflow.com/a/19671818/6085135 Commented Apr 8, 2017 at 18:44
  • w - expense_manager(main project folder contains all the apps and manage.py file etc) requirements.txt Procfile runtime.txt @bren Commented Apr 8, 2017 at 18:54
  • This is the expected file structure github.com/heroku/python-getting-started maybe you can show us your file tree with tree -L 2 stackoverflow.com/questions/3455625/… Commented Apr 8, 2017 at 19:02

For your Procfile try:

web: gunicorn --pythonpath expense_manager wsgi

This is essentially the equivalent of how you'd run:

python expense_manager/wsgi.py

Gunicorn's --pythonpath argument allows you to specify a directory, package name and even module. Like this:

gunicorn --pythonpath <directory> <package>.<module>

Where's your .git folder located? Run ls -a Also maybe doublecheck it's not python-path
