Webpack-dev-server 2 未捕获类型错误：util.inherits 不是函数

Question

当我在编译时运行 webpack-dev-server 时遇到问题而不是控制台错误，但当我转到http://localhost:8080/时在浏览器中抛出下一个错误：

未捕获的类型错误：util.inherits 不是函数。

这很奇怪，因为在没有 webpack-dev-server 的情况下，它可以很好地与 webpack 配合使用。当我调试错误时，错误位于文件 webpack:///./~/websocket-driver/lib/websocket/streams.js?875d 中，错误是此段：

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
