【问题描述】：

我在运行任务时遇到问题。我运行./manage celeryd -B -l info，它正确地将所有任务加载到注册表。

当任何任务运行时都会发生错误 - 任务启动，执行它的操作，然后我得到：

[ERROR/MainProcess] Thread 'ResultHandler' crashed: ValueError('Octet out of range 0..2**64-1',)
Traceback (most recent call last):

    raise ValueError('Octet out of range 0..2**64-1')
ValueError: Octet out of range 0..2**64-1

我还必须注意，这在我之前的 Lion 安装中有效，即使我使用一些测试代码创建了一个空白 virtualenv，当任务运行时它也会出现此错误。

这发生在 Python 2.7.2 和 2.6.4 上。

Django==1.3.1
amqplib==1.0.2
celery==2.4.6
django-celery==2.4.2

【问题讨论】：

什么是delivery_tag？使用 pdb.pm() 进入堆栈跟踪并找出答案。

标签： python django macos celery

【解决方案1】：

homebrew install python 似乎有一些错误。我现在已经切换到原生 Lion 版本 (2.7.1) 并且可以正常工作。

【讨论】：

另外你可以通过 brew upgrade 到 Python 2.7.3 来解决这个问题。
