Module not found: Can't resolve 'redux' in node_modules

Question

When I used typescript to create my react project, I introduced Redux error reporting, which indicated that I could not find it, but I had to install all the dependencies.

Here's my package.json

{
  "name": "react-test",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@types/jest": "^24.0.11",
    "@types/node": "^11.11.3",
    "@types/react": "^16.8.8",
    "@types/react-dom": "^16.8.2",
    "@types/react-redux": "^7.0.3",
    "@types/react-router-dom": "^4.3.1",
    "axios": "^0.18.0",
    "react": "^16.8.4",
    "react-dom": "^16.8.4",
    "react-redux": "^6.0.1",
    "react-router-dom": "^4.4.0",
    "react-scripts": "2.1.8",
    "redux": "^4.0.1",
    "redux-devtools-extension": "^2.13.8",
    "redux-thunk": "^2.3.0",
    "typescript": "^3.3.3333"
  },
  "scripts": {
    "start": "react-app-rewired start",
    "build": "react-app-rewired build",
    "test": "react-app-rewired test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": [
    ">0.2%",
    "not dead",
    "not ie <= 11",
    "not op_mini all"
  ],
  "devDependencies": {
    "babel-plugin-import": "^1.11.0",
    "customize-cra": "^0.2.12",
    "node-sass": "^4.11.0",
    "react-app-rewired": "^2.1.1"
  }
}

Here's my store

import { createStore, applyMiddleware } from 'redux'
import thunk from 'redux-thunk'
import { composeWithDevTools } from 'redux-devtools-extension'

import reducer from './reducer'


const store = createStore(reducer, composeWithDevTools(
   applyMiddleware(thunk)
))

Unfortunately, the app doesn't compile and it complains with:

./node_modules/[email protected]@react-redux/es/connect/mapDispatchToProps.js
Module not found: Can't resolve 'redux' in '~/node_modules/[email protected]@react-redux/es/connect'

What should I do is right. Please help me, thanks.

Answer 1

Try to install both redux and react-redux at same time:

npm install --save redux react-redux

Answer 2

This worked for me

npm install --save redux react-redux

Answer 3

For people that might come across this in the future, I came across the same issue.

I was calling connect(mapStateToProps, null)(Component). All I had to do was actually pass in a proper mapDispatchToProps argument and it solved the problem.

It had nothing to do with redux not being properly installed.

Answer 4

--save means that dependency install as local dependency, that means related for that particular project.

npm install redux -g in here redux install as global dependency
