未捕获的TypeError:无法使用React和Laravel读取未定义的属性'func'

在有人向我推荐其他答案之前-我已经搜索并尝试了所有答案。基本上,我使用Laravel设置了我的第一个React项目,并试图使其将Example.js文件内容注入到welcome.blade.php文件中,但是每次加载页面时,控制台中都会出现以下错误和一个空白页:

Uncaught TypeError: Cannot read property 'func' of undefined
    at Object.exports.__esModule (app.js:667)
    at __webpack_require__ (app.js:20)
    at Object.exports.__esModule (app.js:1598)
    at __webpack_require__ (app.js:20)
    at Object.exports.__esModule (app.js:15798)
    at __webpack_require__ (app.js:20)
    at Object.<anonymous> (app.js:17269)
    at __webpack_require__ (app.js:20)
    at Object.defineProperty.value (app.js:17255)
    at __webpack_require__ (app.js:20)

我进行了研究,发现大多数人说这是一个React-router问题,已在3.2.0版中解决,但是这里不是这种情况,因为我正在使用该版本。我的yarn.lock文件:

react-router@^3.2.0:
  version "3.2.1"
  resolved "https://registry.yarnpkg.com/react-router/-/react-router-3.2.1.tgz#b9a3279962bdfbe684c8bd0482b81ef288f0f244"
  dependencies:
    create-react-class "^15.5.1"
    history "^3.0.0"
    hoist-non-react-statics "^2.3.1"
    invariant "^2.2.1"
    loose-envify "^1.2.0"
    prop-types "^15.5.6"
    warning "^3.0.0"

基本上,我所做的只是将Example.vue文件替换为Example.js文件,并添加了一些简单的内容,然后在app.js文件中规定了使用此组件的路由。然后,我的刀片文件将存储“ example” div。

我正在使用Laravel 5.6,React 16和React Router 3.2.0

如果有人能在正确的方向指点我,我将不胜感激,因为我什至无法完成我的项目,甚至还没有可见的示例页面!

编辑:代码示例

app.js:

require('./bootstrap');

import React from 'react';
import { render } from 'react-dom';
import { Router, Route, browserHistory } from 'react-router';

import Example from './components/Example';

render(
    <Router history={browserHistory}>
        <Route path="/" component={Example} >
        </Route>
    </Router>,
    document.getElementById('example'));

Example.js:

import React, { Component } from 'react';
import ReactDOM from 'react-dom';

class Example extends Component {
    render() {
        return (
            <div>
                <h1>Cool, it's working</h1>
            </div>
        );
    }
}

export default Example;

if (document.getElementById('example')) {
    ReactDOM.render(<Example />, document.getElementById('example'));
}

welcome.blade.php:

<!doctype html>
<html lang="{{ app()->getLocale() }}">
<head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <title>Laravel</title>
    <link href="{{asset('css/app.css')}}" rel="stylesheet" type="text/css">
</head>
<body>
<div id="example"></div>
<script src="{{asset('js/app.js')}}" ></script>
</body>
</html>

请使用react-router代替react-router-dom
