| 我们推荐以这种方式添加 polyfill 而不是在源代码中直接导入它们，因为如果这里列出的 polyfill 在 `browserslist` 的目标中不需要，则它会被自动排除。 | |||

| 3. **如果该依赖交付 ES5 代码，但使用了 ES6+ 特性且没有显式地列出需要的 polyfill (例如 Vuetify)：**请使用 `useBuiltIns: 'entry'` 然后在入口文件添加 `import 'core-js/stable'; import 'regenerator-runtime/runtime';`。这会根据 `browserslist` 目标导入**所有** polyfill，这样你就不用再担心依赖的 polyfill 问题了，但是因为包含了一些没有用到的 polyfill 所以最终的包大小可能会增加。 | |||

babel 文档里写的就是 core-js/stable https://babeljs.io/docs/en/babel-polyfill

好的，发现是版本问题，有的core-js版本没有core-js/stable。使用vue-cli创建的项目使用的core-js有stable包。
