Webpack-dev-server 2 Uncaught TypeError: util.inherits is not a function

问题

I have a problem trying when i run webpack-dev-server not console error in compilation time but throws the next error in browser when i go to http://localhost:8080/:

Uncaught TypeError: util.inherits is not a function.

is strange beacause works well with webpack without webpack-dev-server. when i debug the error the error is in file webpack:///./~/websocket-driver/lib/websocket/streams.js?875d and the error is this segment:

var Stream = require('stream').Stream,
    util   = require('util');


var IO = function(driver) {
  this.readable = this.writable = true;
  this._paused  = false;
  this._driver  = driver;
};
util.inherits(IO, Stream); // this line

webpack.config.js

[ { devtool: 'eval-source-map',
    resolve: { extensions: [Object], modules: [Object], alias: [Object] },
