Vue.js 如何解脚本1003？

关于这个问题也有类似的问题，但似乎没有一个能真正解决这个问题

有一个VueJS项目，用ES6语法构建，用BabeJS传输，然后与Webpack捆绑在一起

这里有一些规格

测试浏览器配置，在这里，它应该在IE11上工作，但它没有

此外，在项目中还使用了引导vue

在我看来，虽然巴贝尔使用的是正确的浏览器列表配置，但在某些情况下，并没有正确地使用它，也许webpack正在覆盖配置

有什么建议吗？ 提前谢谢

更新：

我已经更改了@babel/preset env配置并添加了

Using polyfills with `usage` option:

  When setting `useBuiltIns: 'usage'`, polyfills are automatically imported when needed.
  Please remove the direct import of `core-js` or use `useBuiltIns: 'entry'` instead.
