应用程序测试

app.js

import React, { Component } from 'react';

export default class App extends Component {
    render() {
        return (
            <div style="font-size: 40px">React simple starter</div>
        );
    }
}

import React，{Component}来自'React'；
导出默认类应用程序扩展组件{
render（）{
返回(
简单起动器
);
}
}

它应该在html页面上显示“React simple starter”，但它没有

如果您想查看其他文件，请帮助并让我知道

PS：我对webpack非常陌生

尝试将

babel preset env

和

babel preset react

添加到您的devDependencies中，并删除

babel-preset-es2015

：

纱线添加-d巴别塔预设环境巴别塔预设反应

或

npm安装-d巴别塔预设环境巴别塔预设反应

并更改您的。babelrc：

{
    "presets": [
       ["react"],
       ["env"]
    ],
}

编辑：

尝试按以下方式创建redux应用商店：

const store = createStore(reducers) //assuming reducers is your combined reducers
...
<Provider store={store}>

const store=createStore（reducers）//假设reducers是您的组合reducer
...

而不是：

const createStoreWithMiddleware = applyMiddleware()(createStore);
...
<Provider store={createStoreWithMiddleware(reducers)}>

const createStoreWithMiddleware=applyMiddleware（）（createStore）；
...

OP中的错误似乎表明

index.js

中的代码以编码格式结束在相应的包中。您确定

index.js

在代码

const createStoreWithMiddleware=applyMiddleware（）（createStore）的行上或之后使用了正确的字符吗？
相同的错误？您是否使用webpack dev server
（servicescript-in-your package.json）运行应用程序
const createStoreWithMiddleware = applyMiddleware()(createStore);
...
<Provider store={createStoreWithMiddleware(reducers)}>
