【问题标题】:creatreactapp & Reflux TypeError: Super expression must either be null or a functioncreatreactapp & Reflux TypeError: Super expression must be null or a function
【发布时间】:2019-06-18 20:35:16
【问题描述】:

我有一个简单的 createreactapp,我想用它来测试回流,而不是 redux,我正在尝试将 Reflux 包含在其中。我检查了 .Component 和 .Store 的拼写以及类结构,但仍然。

当我运行它时,它给了我这个错误:

TypeError: Super expression 必须为 null 或函数。

对于 createreactapp 来说,回流是否太旧了? 是 webpack 错误吗? 通天塔?

完全错误:

stateStore.js

import React from 'react';
import actions from './actions';
import Reflux from 'reflux';



class statStore extends Reflux.Store {


    constructor(props){
        super(props);
        this.state = {
            status:0
        }
        this.listenables = actions;




    }


    onStateUpdate2(){

        this.setState({status:2})
        console.log('stateupdate2')
    }


    onStateUpdate3(){

        this.setState({status:3})
        console.log('stateupdate3')
    }




}


export default statStore;

compass.js

import React from 'react';
import actions from './actions';
import statStore from './statStore';
import Reflux from 'reflux';


class Compass extends Reflux.Component {



    constructor(props){
        super(props);
        //this.store = statStore;
    }





    render(){


        console.log('BAHAHHA')

        return(<div onClick={actions.stateUpdate2}>{this.state.status}</div>)



    }



}


export default Compass;

index.js

import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import Compass from './Compass';


ReactDOM.render(<Compass />, document.getElementById('root'));

    【解决方案1】:

    是的,我实际上从 createreactapp 中删除了 serviceWorker,这就是原因。
