Question

我是redux的新手，我创建了一个演示，其中安装了react redux和redux

文件夹结构

  src
    js
      store
        index.js
      action
        index.js
      reducers
        index.js
      index.js  ///////**2**
  index.js ///////////  **1**
  App.js .... etc

在 1 index.js中，我具有以下代码

import index from "./js/index";

在 2 index.js中，我具有以下代码

   import store from "../js/store/index";
   import { addArticle } from "../js/actions/index";

   window.store=store;
   window.addArticle=addArticle;

软件包均已更新当我启动npm时，出现以下错误；

   ./src/js/store/index.js
   Module not found: Can't resolve 'redux' in 'E:\reacr-redux\src\js\store'

js / store / index.js

     import { createStore } from "redux";
     import rootReducer from "../reducers/index";

     const store=createStore(rootReducer);

     export default store;

reducers / index.js

import { ADD_ARTICLE } from "../constants/action-types";
 const initialState={
articles:[]
 };
  const rootReducer= ( state = initialState ,  action ) => {
    switch(action.type){
    case ADD_ARTICLE:
    state.articles.push(action.payload);
    return state;
    default :
    return state;
    }
   };
    export default rootReducer;

package.json

{
"name": "reacr-redux",
"version": "0.1.0",
 "private": true,
 "dependencies": {
"font-awesome": "^4.7.0",
"mdbootstrap": "^4.5.15",
"react": "^16.6.3",
"react-dom": "^16.6.3",
"react-redux": "^5.1.1",
"react-router-dom": "^4.3.1",
"react-scripts": "2.1.1"
 },
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",

 },
 "eslintConfig": {
   "extends": "react-app"
  },
 "browserslist": [
  ">0.2%",
  "not dead",
  "not ie <= 11",
  "not op_mini all"
  ],
 "devDependencies": {
   "redux": "^4.0.1"
   }
  }

任何人都能知道我是怎么回事我在哪里错了

Answer 1

请勿将save-dev用于redux。从devDependencies中将其删除npm卸载redux --save-dev并使用以下命令再次安装：npm i redux --save

Answer 2

只需安装 react toolkit 即可解决问题。

# NPM
npm install @reduxjs/toolkit

# Yarn
yarn add @reduxjs/toolkit

Answer 3

在运行 npm install @reduxjs/toolkit 后尝试重新启动服务器。

为什么我找不到错误模块：无法解决“ redux”
