你好，请原谅我的英语
这个错误很奇怪，直到现在我能够将我的 Django 应用程序和数据库推送到 heroku，这是我的配置

我这样拆分设置:
设置/base.py
from unipath import Path
import os
BASE_DIR = Path(__file__).ancestor(3)
# Quick-start development settings - unsuitable for production
# See https://docs.djangoproject.com/en/1.8/howto/deployment/checklist/

# Application definition
DJANGO_APPS = (

)
LOCAL_APPS = (

THIRD_PARTY_APPS = (
...
)
INSTALLED_APPS = DJANGO_APPS + LOCAL_APPS + THIRD_PARTY_APPS
MIDDLEWARE_CLASSES = (
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',

'django.middleware.clickjacking.XFrameOptionsMiddleware',
'django.middleware.security.SecurityMiddleware',
'corsheaders.middleware.CorsMiddleware',
'django.middleware.common.CommonMiddleware',
)
ROOT_URLCONF = 'proyecto_www.urls'
TEMPLATES = [

},
},
]
WSGI_APPLICATION = 'proyecto_www.wsgi.application'
STATIC_URL = '/static/'
STATICFILES_DIRS=(BASE_DIR,'static',)
MEDIA_URL = '/media/'
MEDIA_ROOT = BASE_DIR.child('media')

TIME_ZONE = 'UTC'
USE_I18N = True
USE_L10N = True
USE_TZ = True
CORS_ORIGIN_ALLOW_ALL = True
CORS_ALLOW_METHODS = (

还有我用于部署的 settings/staging.py
from .base import *
DEBUG_TOOLBAR_PATCH_SETTINGS = False
DEBUG = True
TEMPLATE_DEBUG = True
# Database

# https://docs.djangoproject.com/en/1.8/howto/static-files/
STATIC_ROOT = 'staticfiles'
STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage'
我的 Procfile 是:
web: gunicorn proyecto_www.wsgi --log-file -
我的 wsgi.py 是:
import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "proyecto_www.settings.staging")
from django.core.wsgi import get_wsgi_application
from whitenoise.django import DjangoWhiteNoise
application = DjangoWhiteNoise(get_wsgi_application())
最初的错误是“SECRET_KEY 设置不能为空”
所以我按照这里的答案 Django. Using multiple settings files with Heroku
然后使用命令:
heroku config:set DJANGO_SETTINGS_MODULE=proyecto_www.settings.staging
现在我收到这个错误:

remote: ! Push rejected, failed to compile Python app
请您参考如下方法:
解决方案是从 settings/staging.py 中删除这一行
STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage'
然后像这样更改 wsgi.py:
import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "proyecto_www.settings.staging")
from django.core.wsgi import get_wsgi_application
from dj_static import Cling
application = Cling(get_wsgi_application())
dj_static 库带有 django-toolbelt 或 dj-static
