Question

尝试将反应路由器v4与redux一起使用并遇到此错误，似乎是在关注文档，无法在其上找到任何信息，所以我不知所措：

未捕获的TypeError：无法读取未定义的属性“route”

这是我的代码：

import React, {Component} from 'react';
import {
  BrowserRouter as Router,
  Route,
  Link,
  withRouter
} from 'react-router-dom'
import Menu from './Menu';
import { connect } from "react-redux";
import Play from './Play';
class Manager extends Component {
    render() {
        return(
             <Router>
                <div>
                  <Route exact path="/" component={Menu}/>
                  <Route path="/menu" component={Menu}/>
                  <Route path="/play" component={Play}/>
                </div>
              </Router>
        )
    }
}
export default withRouter(connect(mapStateToProps, mapDispatchToProps)(Manager));

这是完整的错误：

Answer 1

在这里，您使用的是react-router-dom最新版本4.0.0以上。

因此，没有可用的路由器。您需要在此版本中使用BrowserRouter。

您的代码将

import React, {Component} from 'react';
import {
  Switch,
 Route,
 Link,
 withRouter
} from 'react-router-dom'
import Menu from './Menu';
import { connect } from "react-redux";
import Play from './Play';
class Manager extends Component {
   render() {
    return(<div>
         <Switch>

              <Route exact path="/" component={Menu}/>
              <Route path="/menu" component={Menu}/>
              <Route path="/play" component={Play}/>

          </Switch></div>
    )
}
}
 export default withRouter(connect(mapStateToProps, mapDispatchToProps)(Manager));

并在index.js文件中使用BrowserRouter来呈现此Component

import { BrowserRouter } from 'react-router-dom';
ReactDOM.render((<BrowserRouter><Manager/></BrowserRouter>), document.getElementById('root'));

Answer 2

将路由器更改为名为“react-router-dom”

的新路由器4.0

使用npm / yarn安装模块“react-router-dom”，像这样定义你的路由器..

不要忘记进口。从'react-router-dom'导入{BrowserRouter，Route};

         <BrowserRouter>
              <div>
              <Route exact path="/" component={Menu}/>
              <Route path="/menu" component={Menu}/>
              <Route path="/play" component={Play}/>
              </div>
          </BrowserRouter>

您不需要使用比实际路由器更高的withRouter :) 只需删除它：

export default connect(mapStateToProps, mapDispatchToProps)(Manager);

如果要访问嵌套在Route中的组件内的历史信息，则需要使用withRouter HOC。您可以在此处找到详细信息：https://reacttraining.com/react-router/web/api/withRouter

Answer 4

所以我在我的本地服务器上运行它，当我从它运行的webpack服务器上运行它时。

Answer 5

我通过在我的<Navigation />

中移动我的<Router></Router>来解决此问题
