为什么我的django应用无法在heroku上运行？

Question

我正在尝试部署我的heroku应用，但它一直显示以下错误。

remote:          File "/app/.heroku/python/lib/python3.7/site-packages/django/contrib/staticfiles/storage.py", line 43, in path
remote:            raise ImproperlyConfigured("You're using the staticfiles app "
remote:        django.core.exceptions.ImproperlyConfigured: You're using the staticfiles app without having set the STATIC_ROOT setting to a filesystem path.
remote:
remote:  !     Error while running '$ python manage.py collectstatic --noinput'.
remote:        See traceback above for details.
remote:
remote:        You may need to update application code to resolve this error.
remote:        Or, you can disable collectstatic for this application:
remote:
remote:           $ heroku config:set DISABLE_COLLECTSTATIC=1
remote:
remote:        https://devcenter.heroku.com/articles/django-assets
remote:  !     Push rejected, failed to compile Python app.
remote:
remote:  !     Push failed
remote: Verifying deploy...
remote:
remote: !       Push rejected to murmuring-shelf-23422.
 remote:

致https://git.heroku.com/murmuring-shelf-23422.git      ！ [远程拒绝]主机->主机（预接收挂钩被拒绝）      错误：无法将某些引用推送到“ https://git.heroku.com/murmuring-shelf-23422.git”

我猜这是由于缺少静态根，但我已经将其指定为：-
