在运行vue项目时报如下问题：
E:\mobile_real\mobile-vue>npm run dev
> mobile_real@1.0.0 dev E:\mobile_real\mobile-vue
> webpack-dev-server --inline --progress --config build/webpack.dev.conf.js
npm ERR! code ELIFECYCLE

npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the mobile_real@1.0.0 dev script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

查阅资料发现是webpack新版bug，卸载现有webpack，安装老版本即可
解决办法：
1、npm uninstall webpack-dev-server
2、npm install webpack-dev-server@2.9.1
3、npm run dev
vue npm run dev报错webpack-dev-server
