Django 1.6 + Celery 3.1 = TypeError："Settings"对象没有属性"__getitem__"

Question

我正在尝试将芹菜 3.1.0 与 Django 1.6 一起使用。我已经完成了本教程，但是一旦我使用它描述的方法调用芹菜（celery -A proj worker -l info），我就会收到以下错误：

TypeError: 'Settings' object has no attribute '__getitem__'

以前有人遇到过这种情况吗？我错过了什么？

Answer 1

我通过将我的芹菜包绑定到适用于我的 django 应用程序的版本来修复此错误。

这些是引发错误的版本

celery # the newest 
celery==3.1 # main version before the newest

这是对我有用的版本

celery==3.1.25 # the last working version with my app

Answer 2

我用celery==3.1.25来解决问题

Answer 3

芹菜 == 3.1 姜戈 ==

1.10 姜戈-芹菜 == 3.1.17

此版本不能很好地工作
