error screenshot我正在尝试在我的React应用程序中包含React-router,并且在导航组件中使用它,但是在使用它并初始化路径之后,我的react应用程序崩溃了。请参考以下代码:
尝试按照t-router v4语法编写,在App.js文件中使用,在Navigation.js组件中使用Link和Route。
import React,{ Component } from 'react';
import { Route, Link } from "react-router-dom";
import './Navigation.css';
import App from '../../App';
import Create from '../pages/create/Create';
import List from '../pages/list/List';
class Navigation extends Component{
render(){
return (
<div>
<nav className="navbar navbar-expand-md navbar-dark bg-dark">
<Link className="navbar-brand mr-auto" to="/">HOME</Link>
<div id="navbarSupportedContent">
<ul className="navbar-nav">
<li className="nav-item active">
<Link className="nav-link" to="/Create">Create</Link>
</li>
<li className="nav-item" >
<Link className="nav-link" to="/List">List</Link>
</li>
</ul>
</div>
</nav>
{/* <Route path="/" exact component={App} /> */}
<Route path="/Create" component={Create} />
<Route path="/List" component={List} />
</div>
);
}
}
export default Navigation;
App.js:
import React, { Component } from 'react';
import Navigation from './js/navigation/Navigation.js';
import { BrowserRouter as Router } from 'react-router-dom';
class App extends Component {
render() {
return (
<Router>
<div className="App">
<Navigation/>
<div class="jumbotron text-center">
<h1 class="display-4">Welcome</h1>
<hr class="my-4"/>
<p>Please Click on Create to Create the Schema and on List to View the Schema.</p>
</div>
</div>
</Router>
);
}
}
export default App;
当我运行应用程序并单击“创建”或“列表”时,应渲染各个组件,但是当我运行react-app时,应用程序崩溃。

根据崩溃截屏,您的应用正在创建组件中进入无限循环,请检查您的创建组件代码
