WARNING: We noticed you're using the `useBuiltIns` option without declaring a core-js version. Currently, we assume version 2.x when no version is passed. Since this default version will likely change in future versions of Babel, we recommend explicitly setting the core-js version you are using via the `corejs` option.
You should also be sure that the version you pass to the `corejs` option matches the version specified in your `package.json`'s `dependencies` section. If it doesn't, you need to run one of the following commands:
npm install --save core-js@2 npm install --save core-js@3
yarn add core-js@2 yarn add core-js@3
我这几两天才学的 vue,用的 vue cli v3.6 版本,然后编译卡住不动,报这个错,因为当时刚好练习嵌套路由,以为是啥 module 和 router 模块起冲突,真的搞了我一下午,我 google 了半天,关于这个报错的相关数据很少,根本找不到答案,最后仔细看了下代码,就是<template>标签没有根 div,真的是血的教训</template>

今天升级了项目依赖包,给我报了个这个 warn,不过好像没啥影响。。就没管他
明天看看我代码里有没有这个问题。。 |
