scss

npm install node-sass --save-dev        //安装node-sass 
npm install sass-loader --save-dev      //安装sass-loader 
npm install style-loader --save-dev         //安装style-loader

出现以下问题可能是版本错误

Modele build failed: TypeError: this.getResolve is not a function at Object.loader...

处理方法
将 “sass-loader”: “^8.0.0″，更换成了 “sass-loader”: “^7.3.1”

package.json中查找替换

npm install 

npm run dev

Sass报Error: ENOENT: no such file or directory, scandir ‘**/node_modules/node-sass/vendor’

先安装完node-sass看看行不行, 不行的话, 执行:

npm rebuild node-sass

不行的,再运行:
npm update
npm install
node node_modules/node-sass/scripts/install.js
npm rebuild node-sass
npm rebuild gulp-sass
