问题
I'm trying to run my django application on heroku.
Folder structure:
app/
Procfile
docs/
...
project/
manage.py
wsgi.py
<django apps>
Procfile
web: gunicorn --pythonpath="$PWD/project" wsgi:application --log-file=-
Error I'm getting:

Update 1 My wsgi.py file
import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "config")
os.environ.setdefault("DJANGO_CONFIGURATION", "Production")
from configurations.wsgi import get_wsgi_application
application = get_wsgi_application()
Here I am just adding some text because SO has this silly minimum amount of text that must be written in a question. I mean, I do get it that quality needs to be kept, but if the problem is self explanatory why force people to write unneeded text? Thanks and have a great day!
回答1:
Adding --preload to the gunicorn command in the Procfile will make your Traceback a lot more readable and show you the actual errors.
Exmaple:
gunicorn project.wsgi:application --preload --workers 1
回答2:
I had a similar problem, after reading he docs for gunicorn, I was able to add
--log-level debug
to the
web: gunicorn project.wsgi:application --log-file -
such that its
web: gunicorn project.wsgi:application --log-file - --log-level debug
In my case the path was also an issue.

Finally found the solution, it was a missing dependency of django-organizations. I find it crazy that there is no way (at least not that I could find) to see any useful error output from heroku. I finally did
heroku run bash --app <app_name>
and then ran the wsgi.py file line by line, finally getting some meaningful error on
from configurations.wsgi import get_wsgi_application # noqa
It was then clear that it's a missing module error, installed it and everything runs perfectly fine.
回答4:
Change your Procfile to:
web: gunicorn project.wsgi:application --log-file=-
You're missing the project module in the python path to the wsgi.py file.
