高手提供了一个项目框架的VUE模板，同一个项目（同样的工程），我npm run serve时报错，可另个人不会，说明工程项目木有问题，应该是我的环境有问题。各种百度各种让修改项目文件，我觉得木有必要，要对症下药。
报错内容： ERROR Failed to compile with 123 errors （看这么多报错，吓我一跳）

To install them, you can run: npm install --save core-js/modules/ core-js/modules/ core-js/modules/ core-js/modules/-each core-js/modules/ core-js/modules/-of core-js/modules/ core-js/modules/ core-js/modules/ core-js/modules/ core-js/modules/ core-js/modules/ core-js/modules/ core-js/modules/-fixed core-js/modules/ core-js/modules/-string core-js/modules/ core-js/modules/ core-js/modules/ core-js/modules/-string core-js/modules/-with core-js/modules/ core-js/modules/ core-js/modules/ core-js/modules/-with core-js/modules/ core-js/modules/ core-js/modules/ core-js/modules/-each core-js/modules/解决方案：
前面肯定时npm install下载了依赖，那怎么办。要仔细研究报错内容，发现最后一句：To install them, you can run: npm install --save core-js/modules/
是不是少了core-js？试试安装它，再看下一步缺少什么东西，继续装就行（不是缺心眼就行）
所有那就npm install core-js
再nmp run serve
运气真好，发现可以了，欧耶！！！
