python - Traceback (最近一次调用)：...

Question

我试着用Python和tweepy从Twitter上收集数据。

我的代码是：

import tweepy

consumer_key="..."
consumer_secret="..."
access_key = "..."
access_secret = "..."


class CustomStreamListener(tweepy.StreamListener):
    def on_status(self, status):
        print (status.text)

    def on_error(self, status_code):
        print >> sys.stderr, 'Encountered error with status code:', status_code
        return True # Don't kill the stream

    def on_timeout(self):
        print >> sys.stderr, 'Timeout...'
        return True # Don't kill the stream


auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_key, access_secret)
sapi = tweepy.streaming.Stream(auth, CustomStreamListener())
sapi.filter(track=['capital'], async=True) 

在我的控制台中，python return：

RT @gucamo74: @rubenuria eso es muy difícil. El Sevilla no tiene el halo protector arbitral de los equipos de la capital y del Barcelona.
RT @TonySantanaZA: @woznyjs On Macro scale, we failed 2 create Corporate stability, 4 investing Companies. Hence Capital flight,2 other mor… "Pour ne pas se faire rouler"...... #Capital

所以这很好，但在发了几条推文后，他给我看了这条消息：

Exception in thread Thread-10:
Traceback (most recent call last):
  File "//anaconda/lib/python3.5/threading.py", line 914, in _bootstrap_inner
    self.run()
  File "//anaconda/lib/python3.5/threading.py", line 862, in run
    self._target(*self._args, **self._kwargs)
  File "//anaconda/lib/python3.5/site-packages/tweepy/streaming.py", line 286, in _run
    raise
RuntimeError: No active exception to reraise

你知道为什么吗？我希望在我向他求婚之前，气氛不会停止。

我在这篇文章中找到了解决方案：

Unraised exception using Tweepy and MySQL

通过在https://github.com/tweepy/tweepy/blob/master/tweepy/streaming.py上检查tweepy/streaming.py，似乎tweepy在处理异常的方式上有一个bug

if exception:
        # call a handler first so that the exception can be logged.
        self.listener.on_exception(exception)
        raise

此raise应为raise exception

这是魔术，但它有效..。
