Python 将Django应用程序部署到Heroku时出现问题”；未检测到Cedar支持的应用程序”；

我一直在努力按照给出的说明部署一个小型Django web应用程序。在我的开发中，我只使用sqlite3来构建我的应用程序，在Django开发服务器上一切都很好。当我尝试部署到Heroku时，会出现错误“Push-rejected，no Cedar supported app detected”，但我想我已经拥有启动和运行我的应用所需的所有文件。我已经做了几天了，但是没有成功，所以我会接受任何建议和帮助。下面是我的应用程序的草图，但请随时在我的网站上筛选整个应用程序

requirements.txt（使用pip冻结）

runtime.txt

python-3.4.2

对于我的设置文件，我尝试按照

Production.py

from landcrab.settings.base import *
import dj_database_url

DEBUG = False
TEMPLATE_DEBUG = False

# Parse database configuration from $DATABASE_URL
DATABASES['default'] = dj_database_url.config()
# DATABASES['default'] =  dj_database_url.config(default='postgres://user:pass@localhost/dbname')
# DATABASES['default']['ENGINE'] = 'django.db.backends.postgresql_psycopg2'
# DATABASES = {'default': dj_database_url.config(default=os.environ.get('DATABASE_URL'))}
# DATABASES = {'default': dj_database_url.config(default='postgres://localhost')}

# Honor the 'X-Forwarded-Proto' header for request.is_secure()
SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')

# Allow all host headers
ALLOWED_HOSTS = ['*']

最后是wsgi.py

import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "landcrab.settings.production") #Edited by me

from django.core.wsgi import get_wsgi_application

#Added by me for Heroku
try:
    from dj_static import Cling
    application = Cling(get_wsgi_application())
except:
    application = get_wsgi_application()

---

这太尴尬了。在尝试部署到Heroku之前，我没有提交我的更改。提交后，我能够毫无错误地部署。
