 ERROR  Failed to compile with 1 errors                                                                                                     3:29:17 PM

This dependency was not found:

* core-js/modules/es.object.to-string in ./src/router/index.js

To install it, you can run: npm install --save core-js/modules/es.object.to-string

解决办法

babel.config.js文件

presets: [ [ "@vue/app", { useBuiltIns: "entry" } ] ]
