Deploying heroku - Push failed

Question

I need some help to solve this. I don't have much experience with Heroku, this is my first time doing it but I need to deploy some app really quickly. I've tried to disable collectstatic with

heroku config:set DEBUG_COLLECTSTATIC=1 -a name_of_app

But it haven't made any change. Can anyone help me, please ? Here are logs:

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

in your Heroku terminal run heroku config:set DISABLE_COLLECTSTATIC=1, to disable collect static. by default, Heroku will run collectstatic on each deployment

NB: Dissabling collectstatic is a temporary solution.

for a permanent solution, you have to configure static root in settings.py, for example

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')
STATIC_URL = '/static/'
STATICFILES_DIRS = (
    os.path.join(BASE_DIR, 'static'),
)

and after that, you have to run python manage.py collectstatic in your local to make sure everything works locally.

then you can disable collect static with

heroku config:unset DISABLE_COLLECTSTATIC

and you can push your code to heroku with

git push heroku master
