these dependencies were not found core

these dependencies were not found core-js

problem

工程启动后，控制台报错
these dependencies were not found core-js

These dependencies were not found:* core-js/modules/es.array-buffer.constructor.js in ./src/vendor/Export2Excel.js
* core-js/modules/es.array-buffer.slice.js in ./src/vendor/Export2Excel.js

reason

babel配置

solution

修改 babel.config.js

// 修改之后
module.exports = {presets: [ [ "@vue/app", { useBuiltIns: "entry" } ] ]
}
