我在向 Django devserver 发出请求时遇到错误(它在虚拟环境 dj_venv 中运行):
[19/Jul/2016 11:32:40] "GET / HTTP/1.1" 500 59
Traceback (most recent call last):
File "/usr/lib/python2.7/wsgiref/handlers.py", line 85, in run
self.result = application(self.environ, self.start_response)

return func(self._wrapped, *args)
AttributeError: 'Settings' object has no attribute 'ROOT_URLCONF'
奇怪的是，当我启动服务器但没有发出任何请求时，我没有收到任何错误:
daria@daria:~/cms.media$ . ../venvs/dj_venv/bin/activate
(dj_venv) daria@daria:~/cms.media$ python manage.py runserver Validating models...
0 errors found Django version 1.4.11, using settings 'apps.settings' Development server is running at http://127.0.0.1:8000/ Quit the server with CONTROL-C.
但是在第一个请求之后，我得到了一个 AttributeError ，如上所示。
我知道抛出这个错误是因为我的设置对象没有属性“ROOT_URLCONF”，但我已经在我的虚拟环境的 settings.py 和 global_settings.py 中定义了它。我还看了这些文章:
1) 官方文档( ROOT_URLCONF option 和 how Django processes a request )
2) 相关主题:
我检查了以下几点:
1)DJANGO_SETTING_MODULE在manage.py中定义(指向apps.settings)
2) ROOT_URLCONF 在settings.py中定义(指向apps文件夹中的外层urls.py)
3) PyCharm 的 Run > Edit Configuration > Environment variables 添加了 DJANGO_SETTING_MODULE 和 ROOT_URLCONF
有环境变量:
DEFAULT_INDEX_TABLESPACE=1
DJANGO_SETTINGS_MODULE=apps.settings
PYTHONUNBUFFERED=1
ROOT_URLCONF=urls
这是我的项目结构:

还有 setting.py 定义 ROOT_URLCONF:

该异常的原因可能是什么？我已经尝试了在 stackoverflow 中找到的所有内容。我想原因可能是对 settings.py 或 ROOT_URLCONF 的错误引用，我尝试了各种选择，但仍然出现属性错误。
而且我猜想原因可能在中间件中，它可能会在服务器执行请求时重新定义 ROOT_URLCONF(因为在我不向服务器发出任何请求之前没问题)，但我不知道我在哪里可以修复它。
我的猜测是否正确？如果是，我该如何解决我的问题？希望得到任何帮助!
最佳答案
看来您必须将您的应用程序(显然称为“应用程序”)注册到您的 INSTALLED_APPS。
另外，您在 ROOT_URLCONF 中设置了 apps.urls，但只设置了 urls(没有 apps。部分)关于你的环境值(value)观
关于django - 使用 virtualenv 运行应用程序时设置没有属性 ROOT_URLCONF 错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/38464809/
