接受了一个老的项目，做起来真是一个头两个大。
安装错误信息如下：
error code ELIFECYCLE
21 error errno 1
22 error [email protected] dev: `node build/dev-server.js`
22 error Exit status 1
23 error Failed at the [email protected] dev script.
23 error This is probably not a problem with npm. There is likely additional logging output above.
24 verbose exit [ 1, true ]
解决办法：
1、npm cache clean --force
2、rm -rf node_modules
3、rm -rf package-lock.json
4、npm install
