Module not found: Can't resolve 'react-dom' error [Solved]

# Module not found: Can't resolve 'react-dom' error

To solve the error "Module not found: Error: Can't resolve 'react-dom'", make sure to install the react-dom package by opening your terminal in your project's root directory and running the command npm install react-dom react and restart your development server.

Open your terminal in your project's root directory (where your package.json file is located) and run the following commands:

Copied!
# 👇️ with NPM
npm install react-dom react

# 👇️ ONLY If you use TypeScript
npm install --save-dev @types/react-dom @types/react

# ----------------------------------------------

# 👇️ with YARN
yarn add react-dom react

# 👇️ ONLY If you use TypeScript
yarn add @types/react-dom @types/react --dev

The command will add the react-dom package to the dependencies of your project.

You should now be able to import and use the react-dom package in your React.js app.

Copied!
import {StrictMode} from 'react';
import {createRoot} from 'react-dom/client';

import App from './App';

// 👇️ IMPORTANT: use the correct ID of your root element
// This is the ID of the div in your index.html file
const rootElement = document.getElementById('root');
const root = createRoot(rootElement);

root.render(
  <StrictMode>
    <App />
  </StrictMode>,
);

# Delete your node_modules and reinstall your dependencies

If the error is not resolved, try to delete your node_modules and package-lock.json (not package.json) files, re-run npm install and restart your IDE.

If you are on macOS or Linux, issue the following commands in bash or zsh.

Copied!
#  for macOS and Linux
rm -rf node_modules
rm -f package-lock.json
rm -f yarn.lock

# 👇️ clean your npm cache
npm cache clean --force

# 👇️ install packages
npm install

If you are on Windows, issue the following commands in CMD.

Copied!
# for Windows
rd /s /q "node_modules"
del package-lock.json
del -f yarn.lock

# 👇️ clean your npm cache
npm cache clean --force

# 👇️ install packages
npm install

Make sure to restart your IDE and dev server if the error persists. VS Code often glitches and a reboot solves things sometimes.

# Verify you have react-dom installed

If you still get the error, open your package.json file and make sure it contains the react-dom package in the dependencies object.

Copied!
{
  // ... rest
  "dependencies": {
    "react": "^18.0.0",
    "react-dom": "^18.0.0",
  },
  // 👇️ Only if you use TypeScript
  "devDependencies": {
    "@types/react": "^17.0.43",
    "@types/react-dom": "^17.0.14",
  }
}

The react-dom module should NOT be globally installed or be in your project's devDependencies. It should be in the dependencies object in your package.json file.

You can try to manually add the lines and re-run npm install.

Copied!
npm install

Or install the latest version of the package:

Copied!
npm install react-dom@latest react@latest

# 👇️ ONLY If you use TypeScript
npm install --save-dev @types/react-dom@latest @types/react@latest
