问题一： Error occurred while trying to proxy request /uua/api/v1/auth/login from 127.0.0.1:9528 to http://192.168.157.130:8080/B/ (ETIMEDOUT) (nodejs.org/api/errors.…) 第一个情况是因为代理的接口写错，第二个是端口被占用，第三个是node版本低的原因
问题二：
npm ERR! code ELIFECYCLE
npm ERR! errno 134
npm ERR! bomc@0.0.1 dev: webpack-dev-server --inline --progress --config build/webpack.dev.conf.js
npm ERR! Exit status 134

npm ERR! Failed at the bomc@0.0.1 dev script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

新版webpack存在的BUG，卸载现有的新版本webpack，装老版本就好。
（1）、cnpm uninstall webpack-dev-server
（2）、cnpm install webpack-dev-server@2.9.1
（3）、cnpm run dev
