我编写了一个通过 celery 异步运行任务的功能，在本地进行了测试，一切正常。运送到我的暂存环境，当 celery 尝试使用任务时，它会失败并出现以下回溯。
我什至不确定如何调试这个错误，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？

使用 Celery 的 rdb 进入框架，似乎没有设置套接字超时。
(Pdb) self.timeout
<Unset Timeout Value>
有什么办法可以解决这个问题吗？错误来自 Twilio -> httplib2 -> socket.py，它是 _socket 的包装器。这是我的头，甚至不知道如何解决这个问题。
请您参考如下方法:
默认情况下，Twilio 的库将超时设置为:
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 和将 _UnsetTimeoutKls 评估为不同于 None 的实际套接字调用之间一定发生了一些事情。
在初始化 TwilioRestClient 时将超时设置为 None 似乎可以修复错误:
self.client = TwilioRestClient(TWILIO_SID,
TWILIO_AUTH_TOKEN,
timeout=None)
