Uncaught TypeError: Cannot read property 'getCurrentLocation' of undefined

When I run a react-router demo in browser,it reports an error like this:
Uncaught TypeError: Cannot read property 'getCurrentLocation' of undefined
what caused this proble? the version? my codes are like this:
main.js:
import React from "react"; import ReactDOM from "react- import {Router,Route,hashHistory,IndexRoute} from "react-router"; import App from "./Components/App"; ReactDOM.render((<Router hsitory={hashHistory}> <IndexRoute component={App} /> <Route path="/" component={App} /> </Router> ),document.querySelector("#app"));
./Components/App/index.jsx
const APP = React.createClass({ render(){ return( <div> <button>首页</button> {this.props.children} </div> ); } }); export default APP;

Thank you very much!

I found out the problem,it's should be 'history' while I typed as 'hsitory'.
