Sass Loader错误：与API模式不匹配的无效选项对象

我正在将VueJS与VuetifyJS（v2.0.19）框架一起使用。运行npm run serve后出现此错误：

Sass Loader已使用与API模式不匹配的选项对象进行了初始化。

我尝试过的操作：我已经删除了node_modules文件夹，并将所有npm软件包和node.js重新安装/更新为最新的稳定版本。

完整的错误消息：

 error  in ./node_modules/vuetify/src/components/VRangeSlider/VRangeSlider.sass

Module build failed (from ./node_modules/sass-loader/dist/cjs.js):
ValidationError: Invalid options object. Sass Loader has been initialised using an options object that does not match the API schema.
 - options has an unknown property 'indentedSyntax'. These properties are valid:
