我之前发布过这个问题，似乎没有人能够指导我。我想在Python 3上运行tweepy。我现在让它在Python 2上运行。
我按照此页面上的步骤操作
https://github.com/tweepy/tweepy
当我去写作时
python3 setup.py install
我收到它正在下载的消息，这显然意味着它没有正确下载。
为什么它不能在 Python 3 上正确下载？

解决方案：
问题不在于tweepy，而在于python3中的认证，因此要解决此问题，请查看此链接Python 3：SSL：CERTIFICATE_VERIFY_FAILED
然后安装 tweepy 类型 python3 setup.py install
