情况:

日常 cnpm run serve,突然报错

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! demo@0.1.0 serve: `vue-cli-service serve`
npm ERR! Exit status 1
npm ERR! Failed at the demo@0.1.0 serve script.

解决方法：

懒得想了肯定是依赖的问题，打算直接暴力复原（其实对项目没啥影响，不用担心少了啥，因为源文件根本没去动）

1.把项目里的node_modules，也就是依赖包删掉

2.在终端运行cnpm install，重新安装依赖

3.终端运行cnpm run serve

然后？然后就再次进入到日复一日的code环节
