深层错误开启插座.py：TypeError:需要浮点

Question

我写了一个特性，通过芹菜异步运行一个任务，在本地进行了测试，一切都很好。当celery尝试使用这些任务时，它将失败，并返回以下回溯。在

我甚至不知道如何调试这个错误，因为它是由celery调用的，并且发生在python标准库的深处。有什么想法吗？在

使用Celery的rdb进入帧，似乎没有设置套接字超时。在

有什么办法解决这个问题吗？错误来自Twilio->；httplib2->；插座.py它是一个到套接字的包装器。我不知道该怎么解决这个问题。在

Answer 1

事情是这样的：

• 你告诉Twilio库创建一条短信。
• Twilio转到httplib以连接到Twilio服务器。
• httplib连接到Twilio服务器时，设置套接字的超时。

唯一的问题是，由于某些原因，倒数第二个堆栈帧中的self.timeout不是所需的float。您可能需要尝试在Python调试器下运行应用程序，例如：

python -m pdb myapp.py

您将得到一个提示，从中可以键入run来运行应用程序。一旦发生错误，它应该会让您返回到提示。然后，您应该能够键入up，直到到达有问题的帧并查看self.timeout是什么。然后，您可能想四处看看self.timeout是在哪里设置的，以及为什么。然后您应该能够通过修复该问题来解决该问题。在

Answer 2

默认情况下，Twilio的lib将timeout设置为：

class _UnsetTimeoutKls(object):
    """ A sentinel for an unset timeout. Defaults to the system timeout. """
    def __repr__(self):
        return '<Unset Timeout Value>'


# None has special meaning for timeouts, so we use this sigil to indicate
# that we don't care
UNSET_TIMEOUT = _UnsetTimeoutKls()

因此，在实例化TwilioRestClient和实际的socket调用之间一定发生了一些事情，该调用正在将_UnsetTimeoutKls计算为与None不同的东西。在

初始化TwilioRestClient时将timeout设置为None似乎可以修复错误：
