- options has an unknown property ‘data‘. These properties are valid: object { implementation?,

Vue.config.js报错

Syntax Error: ValidationError: Invalid options object. Sass Loader has been initialized using an options object that does not match the API schema.
 - options has an unknown property 'data'. These properties are valid:
   object { implementation?, sassOptions?, prependData?, sourceMap?, webpackImporter? }

Vue3X版本应该要写成

  css: {
    loaderOptions: {
      // 给 sass-loader 传递选项
      sass: {
        prependData: `@import "@/style/index.scss";`
      }
    }
  },

Vue2x的写法

  css: {
    loaderOptions: {
      // 给 sass-loader 传递选项
      sass: {
        // @/ 是 src/ 的别名，引入全局 scss
        data: `@import "@/style/index.scss";`
      }
    }
  },
