npm ERR! Exit status 1

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

原因：这是新版webpack存在的BUG，卸载现有的新版本webpack，装老版本就好。
（1）npm uninstall webpack-dev-server
（2）npm install webpack-dev-server@2.9.1
（3）npm run dev
webpack-dev-server报错
