反应 - 未捕获的类型错误:无法读取未定义的属性“func" [英] React - Uncaught TypeError: Cannot read property 'func' of undefined

问题描述

我收到错误:

<块引用>

未捕获的类型错误:无法读取未定义的属性 'func'

但我不知道为什么，我已经在谷歌上搜索了错误，并给每个人发了同样的错误，但没有运气.谁能帮帮我?

我正在使用 react-router@3.0.2

index.jsx

从'react'导入React；从 'react-dom' 导入 ReactDOM；从反应路由器"导入{路由器，浏览器历史}；从反应头盔"导入{头盔}；从./config/routes"导入路由；ReactDOM.render(<div><头盔><meta charSet='utf-8'/><title>斯凯尔顿</title><link rel='icon' href='images/favicon.png'/><link rel='stylesheet' href='style.css'/></头盔><Router routes={Routes()} history={browserHistory}/>

, document.getElementById('root'));

route.js

从'react'导入React；从反应路由器"导入 { Route, IndexRoute };从 '../pages/Example1' 导入 Example1；出口功能路线(){返回 (<路线><Route path='/' component={Example1}/><IndexRoute 组件={Example1}/></路线>);}导出默认路由；

Example1.js

import React, { Component } from 'react';从 'prop-types' 导入 PropTypes；类 Example1 扩展组件 {使成为() {返回 (<div><h1>你好，世界！这是实施例1.

);}}导出默认示例1；

最初我没有导入 PropTypes，因为我还不需要它.

解决方案

它看起来像一个 react-router 错误(与 prop 类型有关.)它正在开发 react-router 3.2.0

I'm receiving the error:

Uncaught TypeError: Cannot read property 'func' of undefined

Yet I have no idea why, I've Googled the error and gone to everyone post with the same error yet no luck. Can anyone help me out?

I'm using react-router@3.0.2

index.jsx

import React from 'react';
import ReactDOM from 'react-dom';
import { Router, browserHistory } from 'react-router';
import { Helmet } from 'react-helmet';

import Routes from './config/routes';

ReactDOM.render(
    <div>
        <Helmet>
            <meta charSet='utf-8'/>
            <title>Skelton</title>
            <link rel='icon' href='images/favicon.png'/>
            <link rel='stylesheet' href='style.css'/>
        </Helmet>
        <Router routes={Routes()} history={browserHistory}/>
    </div>
, document.getElementById('root'));

route.js

import React from 'react';
import { Route, IndexRoute } from 'react-router';

import Example1 from '../pages/Example1';

export function routes() {
    return (
        <Route>
            <Route path='/' component={Example1}/>
            <IndexRoute component={Example1}/>
        </Route>
    );
}

export default routes;

Example1.js

import React, { Component } from 'react';
import PropTypes from 'prop-types';

class Example1 extends Component {
    render() {
        return (
            <div>
                <h1>Hello World! This is Example 1.</h1>
            </div>
        );
    }
}

export default Example1;

Originally I didn't import PropTypes because I don't need it, yet.

解决方案

It looks like a react-router bug (related to prop types.) It's working on react-router 3.2.0
