Collect Static Error when trying to deploy Django application to heroku

Question

I have put a decent amount of work into my first Django project and I wanted to host it on heroku. I have seen some proposed solutions to this error elsewhere but everything I've tried doesn't seem to fix the error.I've been trying to fix this for 6 hours so I figuered I'd just ask. I'm trying to use whitenoise for the static files. Static files will load fine in my local server, and I can run collect static in my console without any error.

Here is the error

$ python manage.py collectstatic --noinput
       Traceback (most recent call last):

       See traceback above for details.
       You may need to update application code to resolve this error.
       Or, you can disable collectstatic for this application:

First upgrade heroku app by following line heroku stack:set heroku-18 -a <app name> Then git commit --allow-empty -m "Upgraded heroku-18" Then push it git push heroku master It should work ,if it doesn't then delete runtime.txtfile and then commit and push on git and then again try to push by git push heroku master I hope it work for you.
