node-sass安装失败完美解决方法 npm

一、介绍
首先很感谢node-sass安装失败的各种坑这篇教程，给我提供了解决问题的各种方法，但是天不遂人愿，我的情况可能比较特殊，node-sass还是安装不上，下面说下我遇到的情况和解决的方法。
二、问题
gyp错误没有安装我也就忍了，你给我提示个xxx python27 xxx是什么意思？难道nodejs都已经需要python来支持了？什么破错误提示，又长又难看！！这里我不得不吐槽下，浪费了我两天的时间好嘛！，大家不要被它骗了，当然如果你通过上面的链接成功解决了那不算。解决方法在最下面，你也需要看一遍这又长又难看的错误提示，来来一起吐槽吧。
