Warning: Failed prop type: The prop history is marked as required in Router, but its value is undefined.

"react-router": "^5.1.2"

import React from 'react';
import ReactDOM from 'react-dom';
import { Router, Route } from 'react-router'
import './index.css';
import App from './App';
import * as serviceWorker from './serviceWorker';


ReactDOM.render((
  <Router>
    <Route path="/" component={App}/>
    {/* <Route path="/repos" component={Repos}/>
    <Route path="/about" component={About}/> */}
  </Router>
), document.getElementById('root'))
serviceWorker.unregister();

查了好久，都說是版本問題，換了n個(gè)版本，還是會(huì)報(bào)錯(cuò)，后來看到說要從react-router-dom引入，所以安裝了以后,像下面這樣寫，不知道有沒有跟我一樣腦回路不一般。

import { Router, Route } from 'react-router-dom'

依然報(bào)錯(cuò)，對(duì)于我這樣的小白來說真的是很折磨了，后來終于發(fā)現(xiàn)還是格式不對(duì)，主要原因還是由于Router更新api所導(dǎo)致，具體解決方案，參照React api文檔中內(nèi)容 https://reacttraining.com/react-router/web/api/Route 將路由引入方式作出如下修改即可。最后改成這樣終于好了。

import { HashRouter as Router, Route } from 'react-router-dom'

雖然是個(gè)很小的問題，解決了也很高興，我就是這么的容易滿足，不過react-router中還是有很多東西是我不知道的，學(xué)習(xí)的路還很長，加油吧！
