2014-05-07T11:50:06.925753+00:00 app[web.1]: AttributeError: 'Settings' object has no attribute 'ROOT_URLCONF'
在本地它工作正常，在远程bash shell中，似乎django可以访问ROOT_URLCONF，因为我正在运行：
~ $ python manage.py shell
Python 2.7.4 (default, Apr 6 2013, 22:14:13)
In [2]: from django.conf import settings
In [3]: settings.ROOT_URLCONF
Out[3]: 'urls'
因此，manage.py似乎可以访问设置文件，并包含正确的ROOT_URLCONF变量。
我尝试了很多配置而没有运气。有什么想法吗？
以下是我当前的manage.py和设置配置（env变量ENV设置为此处的暂存）：

答案 0 :(得分：4)
问题出现是因为我已从单个设置文件切换到设置包，更新了manage.py中的引用，因此它在本地工作，但没有在wsgi.py中反映出来的是什么在Heroku上配置服务器。
wsgi.py现在设置特定于环境的设置：
os.environ["DJANGO_SETTINGS_MODULE"] = "main.settings." + os.environ["ENV"]
