你在Python3中吗？ – Anzel 2014-11-03 12:17:38

没有在Py2.7，因为你也可以看到在错误 – Volatil3 2014-11-03 12:19:18

我知道一些模块被拆分为Python3的** urllib2 **。 – Anzel 2014-11-03 12:21:21

这是SO问题得到了几个答案Python ImportError: cannot import name HTTPSHandler。

一般情况下，检查您是否安装了ssl模块和OpenSSL头文件。

这是真的我的SSL被破坏并重新安装。我应该通过Homebrew再次安装python吗？ – Volatil3 2014-11-03 13:34:02

你不应该需要，你在virtualenv？ – Anzel 2014-11-03 14:08:50

不，我不是。我用openssl重新安装Python，现在就可以工作。 – Volatil3 2014-11-03 16:03:39
