import 'assets/scss/index.scss' 引入这个会报错呀，什么原因呢

我在main.js里面引入：

import 'assets/scss/index.scss'

然后浏览器就会报错，报错内容如下：

[WDS] Errors while compiling. Reload prevented.

./node_modules/css-loader??ref--9-1!./node_modules/postcss-loader/lib??ref--9-2!./node_modules/.8.0.2@sass-loader/dist/cjs.js??ref--9-3!./src/assets/scss/index.scss

Module build failed: TypeError: this.getResolve is not a function

这是什么原因呢编译失败，已阻止重新加载  求解决方法
