记录一下问题：mac电脑进行webpack部署的时候产生的问题，webpack版本不兼容的问题，本地电脑webpack用最新的有问题。
sh: webpack-dev-server: command not found
npm ERR! code ELIFECYCLE
npm ERR! syscall spawn
npm ERR! file sh
npm ERR! errno ENOENT
npm ERR! [email protected] dev: `webpack-dev-server`
npm ERR! spawn ENOENT
npm ERR!
npm ERR! Failed at the [email protected] dev script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

解决方案：
1. 更换webpack版本，更换webpack-dev-server版本（webpack-dev-server版本在项目里面好像找不到，后面试了3.6.0发现报错不行）
sudo npm i [email protected] -g
sudo npm i [email protected] -g
2.更新完之后，重新安装package.json的依赖环境
rm -rf ./node_modules
npm install
3.如果执行时报错加sudo试试，可能是权限问题
