node-sass安装失败问题解决

全局安装依赖的时候，因为node-sass报错

Module build failed (from .[表情]de_modules/mini-css-extract-plugin/dist/loader.js):
ModuleBuildError: Module build failed (from .[表情]de_modules[表情]ss-loader[表情]b/loader.js):

　尝试了先卸载node-sass 

npm uninstall node-sass

  再安装

npm i node-sass

　还是报错，这次貌似跟Python相关但是不用管它

　　使用下面的方法 这次终于成功了
