react 路由器 v^4.0.0 未捕获的类型错误: 无法读取未定义的属性“位置”
2022-08-30 04:23:25
我在react路由器上遇到了一些问题(我使用的是版本^4.0.0)。
这是我的索引.js
import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import './index.css';
import { Router, Route, Link, browserHistory } from 'react-router';
ReactDOM.render(
<Router history={browserHistory} >
<Route path="/" component={App} />
</Router>,
document.getElementById('root')
);
应用程序.js就是任何东西。我在这里发布基本一个,因为这不是问题(我相信)
import React, { Component } from 'react';
import logo from './logo.svg';
import './App.css';
class App extends Component {
render() {
return (
<div className="App">
<div className="App-header">
<img src={logo} className="App-logo" alt="logo" />
<h2>Welcome to React</h2>
</div>
<p className="App-intro">
To get started, edit <code>src/App.js</code> and save to reload.
</p>
</div>
);
}
}
export default App;
这就是我检查控制台日志时发生的事情
Router.js:43 Uncaught TypeError: Cannot read property 'location' of undefined

哦,这是 package.json 以防万一
{
"name": "teste2",
"version": "0.1.0",
"private": true,
"dependencies": {
"react": "^15.4.2",
"react-dom": "^15.4.2",
"react-router": "^4.0.0"
},
"devDependencies": {
"react-scripts": "0.9.5"
},
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject"
}
}
我一直在其他地方检查这个问题,但我没有找到解决它的方法。
非常感谢你们的耐心和帮助!!
