vue-element-admin项目编译时报错： ERROR Failed to compile with 121 errors 解决方案

总之100多个错MP，先骂开发100遍，啥也不是

今天jenkins在发布一个新项目时报了一大堆错，于是乎我在测试环境中手动测试下来也报了不同的错误，问前端开发人员，他说IDE环境中正常，说可能你打包环境问题，MP，我把node升到和开发一样，结果报了如题错误，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 121 errors （看这么多报错，吓我一跳）

npm install执行完毕了，按说该要的包都安装好了，正在执行npm run build:test时崩了，MP

我想应该是缺少core-js包

于是乎提着大刀去找开发，这下没话说了，在package添加依赖吧
问题解决
