Javascript 无法获取属性'；地点'；react路由器中未定义或空引用的

我正在react路由器上做一个非常简单的程序…但我不知道这是怎么回事…这是我的react路由器代码

index.js

    import React, { Component } from 'react';
    import ReactDOM from 'react-dom';
    import { Router, browserHistory} from 'react-router';
    import routes from './routes';


    ReactDOM.render(
        <Router history={browserHistory} routes={routes} />
      , document.querySelector('.container'));

    import React, { Component } from 'react';
    import { Route, IndexRouter } from 'react-router';
    import App from './components/app';

    export default(
      <Route path="/" component={App} />
    );

import React from "react";

const App = props => {
  return <div>HI</div>;
};

export default App;

import React from "react";
import { Route, Switch } from "react-router-dom";
import App from "./app";

const Routes = props => {
  return (
    <div>
      <Switch>
        <Route exact path="/" component={App} />
      </Switch>
    </div>
  );
};

export default Routes;

import React from "react";
import ReactDOM from "react-dom";
import { BrowserRouter } from "react-router-dom";
import Routes from "./routes";

ReactDOM.render(
  <BrowserRouter>
    <Routes />
  </BrowserRouter>,
  document.querySelector(".container")
);

import React，{Component}来自'React'；
从“react dom”导入react dom；
从“react Router”导入{Router，browserHistory}；
从“./routes”导入路由；
ReactDOM.render(
，document.querySelector（'.container'）；

这是路由文件

routes.js

    import React, { Component } from 'react';
    import ReactDOM from 'react-dom';
    import { Router, browserHistory} from 'react-router';
    import routes from './routes';


    ReactDOM.render(
        <Router history={browserHistory} routes={routes} />
      , document.querySelector('.container'));

    import React, { Component } from 'react';
    import { Route, IndexRouter } from 'react-router';
    import App from './components/app';

    export default(
      <Route path="/" component={App} />
    );

import React from "react";

const App = props => {
  return <div>HI</div>;
};

export default App;

import React from "react";
import { Route, Switch } from "react-router-dom";
import App from "./app";

const Routes = props => {
  return (
    <div>
      <Switch>
        <Route exact path="/" component={App} />
      </Switch>
    </div>
  );
};

export default Routes;

import React from "react";
import ReactDOM from "react-dom";
import { BrowserRouter } from "react-router-dom";
import Routes from "./routes";

ReactDOM.render(
  <BrowserRouter>
    <Routes />
  </BrowserRouter>,
  document.querySelector(".container")
);

import React，{Component}来自'React'；
从“react router”导入{Route，IndexRouter}；
从“./components/App”导入应用程序；
导出默认值(
);

它显示了类似这样的错误。。。

您需要使用

react-router-dom

而不是

react-router

。我已经创建了基本代码沙盒，您可以在这里检查代码

App.js

    import React, { Component } from 'react';
    import ReactDOM from 'react-dom';
    import { Router, browserHistory} from 'react-router';
    import routes from './routes';


    ReactDOM.render(
        <Router history={browserHistory} routes={routes} />
      , document.querySelector('.container'));

    import React, { Component } from 'react';
    import { Route, IndexRouter } from 'react-router';
    import App from './components/app';

    export default(
      <Route path="/" component={App} />
    );

import React from "react";

const App = props => {
  return <div>HI</div>;
};

export default App;

import React from "react";
import { Route, Switch } from "react-router-dom";
import App from "./app";

const Routes = props => {
  return (
    <div>
      <Switch>
        <Route exact path="/" component={App} />
      </Switch>
    </div>
  );
};

export default Routes;

import React from "react";
import ReactDOM from "react-dom";
import { BrowserRouter } from "react-router-dom";
import Routes from "./routes";

ReactDOM.render(
  <BrowserRouter>
    <Routes />
  </BrowserRouter>,
  document.querySelector(".container")
);

从“React”导入React；
const App=props=>{
返回HI；
};
导出默认应用程序；

Routes.js

    import React, { Component } from 'react';
    import ReactDOM from 'react-dom';
    import { Router, browserHistory} from 'react-router';
    import routes from './routes';


    ReactDOM.render(
        <Router history={browserHistory} routes={routes} />
      , document.querySelector('.container'));

    import React, { Component } from 'react';
    import { Route, IndexRouter } from 'react-router';
    import App from './components/app';

    export default(
      <Route path="/" component={App} />
    );

import React from "react";

const App = props => {
  return <div>HI</div>;
};

export default App;

import React from "react";
import { Route, Switch } from "react-router-dom";
import App from "./app";

const Routes = props => {
  return (
    <div>
      <Switch>
        <Route exact path="/" component={App} />
      </Switch>
    </div>
  );
};

export default Routes;

import React from "react";
import ReactDOM from "react-dom";
import { BrowserRouter } from "react-router-dom";
import Routes from "./routes";

ReactDOM.render(
  <BrowserRouter>
    <Routes />
  </BrowserRouter>,
  document.querySelector(".container")
);

从“React”导入React；
从“react router dom”导入{Route，Switch}；
从“/App”导入应用程序；
const Routes=props=>{
返回(
);
};
导出默认路径；

index.js

    import React, { Component } from 'react';
    import ReactDOM from 'react-dom';
    import { Router, browserHistory} from 'react-router';
    import routes from './routes';


    ReactDOM.render(
        <Router history={browserHistory} routes={routes} />
      , document.querySelector('.container'));

    import React, { Component } from 'react';
    import { Route, IndexRouter } from 'react-router';
    import App from './components/app';

    export default(
      <Route path="/" component={App} />
    );

import React from "react";

const App = props => {
  return <div>HI</div>;
};

export default App;

import React from "react";
import { Route, Switch } from "react-router-dom";
import App from "./app";

const Routes = props => {
  return (
    <div>
      <Switch>
        <Route exact path="/" component={App} />
      </Switch>
    </div>
  );
};

export default Routes;

import React from "react";
import ReactDOM from "react-dom";
import { BrowserRouter } from "react-router-dom";
import Routes from "./routes";

ReactDOM.render(
  <BrowserRouter>
    <Routes />
  </BrowserRouter>,
  document.querySelector(".container")
);

从“React”导入React；
从“react dom”导入react dom；
从“react router dom”导入{BrowserRouter}；
从“/Routes”导入路由；
ReactDOM.render(
,
文档查询选择器（“容器”）
);

这是完整的代码吗？@Sandip Nirmal是的，它没有简单的App.js文件，我没有包含在其中。您需要创建历史对象并将其传递给组件，而不是传递导入的模块。检查包含的路由器版本是否有历史模块。如果不将路由器更新到具有且tryit显示错误的版本，则类似这样的情况无法获取未定义或空引用的属性func，您可以将应用程序组件设置为基于类吗component@mrpanchal完成。我不知道你面临什么问题。谢谢你给我时间，但我不知道为什么我的浏览器不能正常工作
