我正在尝试从本教程tulane.edu-twitter运行以下脚本，我收到以下错误：

我还尝试按照youtube上的教程进行操作，我遇到了同样的错误：

几天前它完美运行（仍然有.csv它返回）。但是现在和我尝试过的其他脚本一样，使用.filter方法时会出现多个错误。如果我将.filter()替换为.sample()，则可行。我唯一记得的就是做一个可能破坏某事的brew update。
这里是第一个提到的教程试图过滤西班牙语推文的代码。
任何想法如何解决这个问题？
import tweepy

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

API_SECRET = ''

ACCESS_TOKEN_SECRET = ''
key = tweepy.OAuthHandler(API_KEY, API_SECRET)
key.set_access_token(ACCESS_TOKEN, ACCESS_TOKEN_SECRET)
api = tweepy.API(key)

self.api = api or API()

self.n = self.n+1
if self.n < self.m:
return True
else:
print 'tweets = '+str(self.n)
return False
stream = tweepy.streaming.Stream(key, Stream2Screen())
stream.filter(track=['de'], languages=['es'])
# stream.sample()
