Redux TypeError:无法读取未定义的属性“应用" [英] Redux TypeError: Cannot read property 'apply' of undefined

问题描述

我已经禁用了 react devtools 和 redux devtools.

I have disabled react devtools and redux devtools.

数小时以来，我一直在寻找解决此问题的方法，大多数问题都在撰写中，而我根本不更改代码.

I've been searching for ways to deal with this problem for hours, and most of the problems are in compose while I don't change code at all.

import { createStore, applyMiddleware,compose } from 'redux';
import thunk from 'redux-thunk';
import rootReducer from './reducers';

const initialState={};

const middleware = [thunk];

const store = createStore(rootReducer,initialState,
    compose(
        applyMiddleware(...middleware),
        window.__REDUX_DEVTOOLS_EXTENSION__&& window.__REDUX_DEVTOOLS_EXTENSION__()
        )   
    );


export default store;

我真的不明白为什么会这样.我没有改变任何东西，我做的最后一件事就是将 git push origin master 执行到我的存储库，突然当我编译时我收到了这个错误:

I really don't understand why this happened. I don't change anything and the last thing I do is just do git push origin master to my repository and suddenly when I compiled I got this error:

我在我的前端使用这个:

推荐答案

将您的 redux 开发工具从 2.16.0 更新到 2.16.1

Update your redux dev tools from 2.16.0 to 2.16.1

或

从你的代码中删除这一行

Remove this line from your code

window.__REDUX_DEVTOOLS_EXTENSION__&& window.__REDUX_DEVTOOLS_EXTENSION__()
