javascript - React redux applyMiddleware 不是一个函数

Question

我自己无法发现我的代码中的任何缺陷，我遇到了错误

Uncaught TypeError: (0 , _reactRedux.applyMiddleware) is not a function

import { applyMiddleware, createStore } from 'react-redux'
import { promiseMiddleware } from './middleware'

const defaultState = {
    appName: 'conduit',
}

const reducer = (state = defaultState, action) => {
    switch(action.type) {
        case 'HOME_PAGE_LOADED':
            return { ...state, articles: action.payload.articles }
    }
    return state
}

const middleware = applyMiddleware(promiseMiddleware)

const store = createStore(reducer, middleware)

export default store

知道出了什么问题吗？

您的进口混淆了。 createStore 和 applyMiddleware 是主 Redux 包的一部分，而不是 React-Redux。您需要:

import {createStore, applyMiddleware} from "redux";
