vue 使用 scss （解决 Module build failed: TypeError: loaderContext.getResolve is not a function）

1.安装sass 依赖包  终端输入

npm  install sass-loader --save-dev

npm install node-sass --sava-dev

2.build文件夹下的webpack.base.conf.js的rules里面添加配置

{

  test: /\.scss$/,

  loaders: ['style', 'css', 'sass']

}

3.使用scss时候在所在的style样式标签上添加lang=”scss”即可 

4.scss使用

<style lang="scss">

$color:red;

.home{

  div {color:$color;}

}

</style>

可能会出现的问题

 这个就是sass-loader版本过高  只需要降低版本即可

卸载sass-loader ： npm uninstall sass-loader

安装指定版本： npm install sass-loader@7.3.1 --save
