无法从twython导入Twython: ProtocolError和name certs错误

Question

在使用python时，我在导入twython时遇到了困难。安装似乎很好，但出于某种原因，我在下面看到了以下错误。当我第一次尝试导入时，我会得到错误"ImportError:无法导入名称ProtocolError“，随后的每一次尝试都会导致以下错误"ImportError:无法导入名称证书”。也许有一个简单的解决办法，但我不知所措。

这似乎是这个问题的一个表现：https://github.com/kennethreitz/requests/issues/2028

我通过重新安装请求来解决这个问题：pip uninstall requests和pip install requests
