环境：python 2.7.10 tweepy:3.5.0
错误：tweepy.error.TweepError: Failed to send request: [SSL: UNKNOWN_PROTOCOL] unknown protocol (_ssl.c:590)

代码：网上一个demo
import re
import tweepy

auth = tweepy.OAuthHandler("xxxxx",

                       "xxxxx")  

auth.set_access_token("xxxxx",

                  "xxxxx")   

api = tweepy.API(auth,proxy="127.0.0.1:1080")
highpoints = re.compile(u'uD800-uDBFF')
public_tweets = api.home_timeline()
num = 0
for tweet in public_tweets:

print num  
num += 1  
text_noem = highpoints.sub('--emoji--', tweet.text)  
text_noem = text_noem.encode('utf8')

求大神指点，什么原因呢？
