我正在尝试安装 django-notification 应用程序[1]，当我提供 manage.py syncdb 时出现错误。

错误状态：EnvironmentError: NOTIFICATIONS was not found.

我已经使用安装工具成功安装了 django-notification。这是我的堆栈跟踪。

EnvironmentError: NOTIFICATIONS was not found.

任何想法出了什么问题？

*添加了 settings.INSTALLED_APPS 部分（按照建议将“django-notifications”条目更正为“通知”）*

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'grappelli',
    'filebrowser',
    'tinymce',
    'south',
    'avatar',
    'django.contrib.admin',
    'notification',
    'myproject.main',
)

【解决方案1】：

无论出于何种原因，您决定将django_notifications 添加到settings.INSTALLED_APPS 而不是notification。解决这个问题。

【讨论】：

起初我的 settings.INSTALLED_APPS 中有“通知”。这就是我得到的。 raise ImproperlyConfigured('ImportError %s: %s' % (app, e.args[0])) django.core.exceptions.ImproperlyConfigured: ImportError notification: No module named notification
那么您断言 django-notification 已成功安装是可疑的。
谢谢。你是对的。虽然应用程序安装成功，但我安装了错误的应用程序。似乎在存储库中有一个 django-notifications 应用程序可以做其他事情。因此，我没有安装django-notification 应用程序，而是安装了django-notifications 应用程序。我觉得很尴尬。 :-)
