pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

解决方案
最开始在网上搜索同类问题，大都是说python 的ssl模块未安装，从问题描述来看确实也很像，但是他们的问题大多发生在Linux上，而我的是Windows，又联想到Anaconda本来就是一个Python的套件包，包含了许多常用的工具和Python库，不可能犯这种低级错误，所以很可能是环境变量未配置全，导致pip无法找到ssl相关模块。
最终参考之前正常的Anaconda的配置，将”[Anaconda安装目录]\Library\bin”加入PATH后，问题解决。
