Sass Loader报错：ValidationError: Invalid options object. Sass Loader has been initialised using an options object that does not match the API schema.

在vue.config.js中引入sass全局配置后报错
vue.config.js代码如下：

module.exports = {
  devServer: {
    port: 3333,
    open: true
  },
  css: {
    loaderOptions: {
      sass: {
        data: `@import "@/assets/scss/_variable.scss";`
      }
    }
  }
}

_variable.scss的代码如下：

$theme-color: #33aef0;

组件中的scss代码如下：

<style lang="scss">
#app {
  color: $theme-color;
  height: 100vh;
}
</style>

页面报错如下：

./src/assets/scss/reset.scss (./node_modules/css-loader/dist/cjs.js??ref--8-oneOf-3-1!./node_modules/postcss-loader/src??ref--8-oneOf-3-2!./node_modules/sass-loader/dist/cjs.js??ref--8-oneOf-3-3!./src/assets/scss/reset.scss)
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 ‘data‘. These properties are valid:
   object { implementation?, sassOptions?, prependData?, sourceMap?, webpackImporter? }
    at validate (E:\element-ui\vue-manage-system\node_modules\schema-utils\dist\validate.js:85:11)
    at Object.loader (E:\element-ui\vue-manage-system\node_modules\sass-loader\dist\index.js:36:28)

解决办法：
将data改成prependData

// 旧
data: `@import "~@/assets/scss/variables.scss";`
// 新
prependData: `@import "~@/assets/scss/variables.scss";`
