[Django]-Why gunicorn cannot find static files?

From Deploying static files in the Django documentation, you must run the collectstatic command in addition to setting the STATIC_ROOT setting.

First make sure that you’re STATIC_ROOT is set to the correct path that matches your nginx config:

STATIC_ROOT = '/home/django/innovindex/pubmed/static/'

Note that this is an absolute path.

Then run:

python manage.py collectstatic

in your project directory.

This will copy all of your static files into /home/django/innovindex/pubmed/static/

I spent a lot of time trying to figure this out until I found that the below must be in your main urls.py. Just add those two lines.

from django.contrib.staticfiles.urls import staticfiles_urlpatterns

# ... 

urlpatterns += staticfiles_urlpatterns()
