如何修复 react-redux 解决问题？

Question

I recently study about redux.

I install redux below

npm install -save redux @types/react-redux

I keep try to fix this problem... but is not working

This is my dependencies

"dependencies": {
    "@testing-library/jest-dom": "^5.11.4",
    "@testing-library/react": "^11.1.0",
    "@testing-library/user-event": "^12.1.10",
    "@types/jest": "^26.0.15",
    "@types/react": "16.14.2",
    "@types/react-dom": "16.9.10",
    "@types/react-redux": "7.1.14",
    "firebase": "8.2.0",
    "node-sass": "4.14.1",
    "query-string": "6.13.7",
    "react": "^17.0.1",
    "react-dom": "^17.0.1",
    "react-router-dom": "5.2.0",
    "react-scripts": "4.0.1",
    "redux": "4.0.5",
    "typescript": "^4.0.3",
    "web-vitals": "^0.2.4"
  },

error

./src/index.tsx
Modules not found : Can't resolve 'react-redux' ...

and this is my index.tsx

import React from 'react';
import ReactDOM from 'react-dom';
import rootReducer from './testsrc/modules';
import {createStore} from 'redux';
import {Provider} from 'react-redux';
import CounterContainer from './testsrc/container/CounterContainer';


const store = createStore(rootReducer);


ReactDOM.render(
  <Provider store={store}>
    <CounterContainer/>
  </Provider>,
  
  document.getElementById('root')
);

How can I fix this?

Answer 1

You just need to install redux and react-redux by running the command

  npm install --save redux @types/redux

and

npm install --save react-redux @types/react-redux

Answer 2

you need to install react-redux too. using this code:

npm install react-redux

Answer 3

Your dependencies doesn't contain a react-redux , therefore your system doesn't see that as installed.

Try:

npm install react-redux
