TweepError：预期长度，发现意外值 pandas jupyter notebook

Question

这是我的代码，试图初始化一个类的实例，我得到一个 Tweep 错误

query = 'vacation'
max_tweets = 1000

myStreamListener = MyStreamListener()
myStream = tweepy.Stream(auth = api.auth, listener = myStreamListener)
myStream.filter(track=[query])

返回的错误如下所示：

TweepError                                Traceback (most recent call last)
<ipython-input-31-227d7853c42e> in <module>()

TweepError: Expecting length, unexpected value found

我尝试对此进行一些研究，但运气不佳，非常感谢您的帮助！谢谢！

我正在使用 tweepy 库的克隆版本（因为开发团队尚未将最新版本推送到 pip 并且以前的版本不时抛出 Nonetype 错误）。我多次遇到同样的错误。错误在以下方法中：

def _read_loop(self, resp):
    charset = resp.headers.get('content-type', default='')
    enc_search = re.search('charset=(?P<enc>\S*)', charset)
    if enc_search is not None:
        encoding = enc_search.group('enc')
    else:
        encoding = 'utf-8'

    buf = ReadBuffer(resp.raw, self.chunk_size, encoding=encoding)

    while self.running and not resp.raw.closed:
        length = 0
        while not resp.raw.closed:
            line = buf.read_line()
            if not line:
                self.listener.keep_alive()  # keep-alive new lines are expected
            elif line.strip().isdigit():
                length = int(line)
                break
            else:
                raise TweepError('Expecting length, unexpected value found')

        next_status_obj = buf.read_len(length)
        if self.running and next_status_obj:


self._data(next_status_obj)

我换了

raise TweepError('Expecting length, unexpected value found')

with

self.listener.keep_alive()

到目前为止它工作正常，但最终 tweepy 开发团队需要解决这。
