使用webpack-dev-server 自动打包时出现的问题

代码如下：

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! [email protected] dev: `webpack-dev-server`
npm ERR! Exit status 1
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.

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\LENOVO\AppData\Roaming\npm-cache\_logs\2019-08-19T03_04_01_541Z-debug.log

总结原因：webpack-dev-server的版本太高，3.以上的不行。降到2.11.3一下左右即可。
