关于npm/node-sass安装依赖报错的解决方案

每次拉新项目安装依赖的时候，总是会报各种各样的错误

npm install

一开始还以为是哪个文件有问题，后来明白了，一切都是因为网络。。。。
npm 默认连接的服务器是国外的，网络很不稳定。。。。所以极其容易出错

后来每次换电脑，我都会直接将npm连接的服务器设置为淘宝源（淘宝架设的与npm官方同步数据的服务器）国内访问丝滑流畅

npm config set registry https://registry.npm.taobao.org

可是后来还是遇到了问题
仔细看报错信息，是node-sass下载失败了。
我以为是node-sass版本问题，后来以为是node的版本问题（node太新的话，不兼容老版本node-sass）
但我还是栽了。。。。。，它依然还是网络问题！！！

仔细看下面安装Node-sass时的报错信息

Downloading binary from https://github.com/sass/node-sass/releases/download/v4.11.0/win32-x64-72_binding.node
Cannot download "https://github.com/sass/node-sass/releases/download/v4.11.0/win32-x64-72_binding.node":

HTTP error 404 Not Found

Hint: If github.com is not accessible in your location
      try setting a proxy via HTTP_PROXY, e.g.

      export HTTP_PROXY=http://example.com:1234

or configure npm proxy via

      npm config set proxy http://example.com:8080

发现没有

Cannot download "https://github.com/sass/node-sass/releases/download/v4.11.0/win32-x64-72_binding.node":

无法下载，地址是什么？ https://github.com/
回忆一下，我们平时上gayhub时的卡顿酸爽？
是的，node-sass在安装过程中，有一步是下载win32-x64-72_binding.node这个文件，而它请求的是github地址，所以我们现在要把这个地址也替换成淘宝源

npm install -g mirror-config-china --registry=http://registry.npm.taobao.org

设置好以后，我们进行

npm install

大功告成！(看Downloading的地址是不是变成了taobao.org)

综合起来就是

npm config set registry https://registry.npm.taobao.org
npm install -g mirror-config-china --registry=http://registry.npm.taobao.org
npm install

不是我针对谁，在座的报错，都是垃圾！！！
