使用OAuthHandler类时出现错误：AttributeError：身份验证实例没有属性'apply_auth'

我是python的新手，我使用tweepy库进行twitter流式处理，我正在尝试创建一个为我处理OAth身份验证的类 .

from config.config import consumer_secret, consumer_key, secret, token
import tweepy
from tweepy.auth import OAuthHandler
from tweepy import API
from tweepy import OAuthHandler


class Authentication:
    """
    Class that handles the authentication for streaming
    http://docs.tweepy.org/en/v3.5.0/auth_tutorial.html
    """

    def __init__(self):
        self.consumer_key = consumer_key
        self.consumer_secret = consumer_secret
        self.secret = secret
        self.token = token

    def getAuthorization(self):
        self.consumer_key = consumer_key
        self.consumer_secret = consumer_secret
        self.secret = secret
        self.token = token
        auth = OAuthHandler(self.consumer_key, self.consumer_secret)
        auth.set_access_token(self.token, self.secret)
        return auth

我有另一个实现Twitter Streaming的类

import tweepy
from tweepy.streaming import StreamListener
from tweepy import Stream
from tweepy.auth import OAuthHandler


class Listener(tweepy.StreamListener):
    """
    Class that inherits from tweepy StreamListener
    http://tweepy.readthedocs.io/en/v3.5.0
    """

    def on_status(self, status):
        print status
        print(status.text)

    def on_data(self, data):
        print data
        return True

    def on_error(self, status):
        if status == 420:
            # returning False in on_data disconnects the stream
            print status
            return False

问题是当我尝试在主类上访问myStream的方法时，例如My Stream Filter，我得到以下错误：

# main  class for the bigDataTweetListener project
import tweepy
from tweepy import Stream
from lib.authentication import Authentication
from lib.tweetListener import Listener
from tweepy.auth import OAuthHandler

# API Authentication
auth = Authentication()
auth.getAuthorization()
api = tweepy.API(auth)
print("authorization  successful")

#Listen a Stream by topic
myStreamListener = Listener()
myStream = tweepy.Stream(auth=api.auth, listener=myStreamListener)
myStream.filter(track="world  cup")

回溯（最近一次调用最后一次）：文件"C:/Users/Sosa9/PycharmProjects/bigDataTweetListener/main.py"，第17行，在myStream.filter（track = "world cup"）文件"C:\Users\Sosa9\PycharmProjects\bigDataTweetListener\venv\lib\site-packages\tweepy\streaming.py"，第228行，在过滤器self._start（async）文件"C:\Users\Sosa9\PycharmProjects\bigDataTweetListener\venv\lib\site-packages\tweepy\streaming.py"，第172行，在_start self._run（）中文件"C:\Users\Sosa9\PycharmProjects\bigDataTweetListener\venv\lib\site-packages\tweepy\streaming.py"，第105行，在_run self.auth.apply_auth（url，'POST'，self.headers，self.parameters）中AttributeError：身份验证实例没有属性'apply_auth'

我不知道为什么如果我已授予访问权限来创建身份验证类的实例，那么来自流类的methods.attributes是不可访问的 . 有任何想法吗？
