# Module not found: Can't resolve 'react-bootstrap'

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

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

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

# 👇️ with YARN
yarn add react-bootstrap bootstrap

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

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

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

Copied!
import {Button, Badge} from 'react-bootstrap';
import 'bootstrap/dist/css/bootstrap.min.css';

// or
// import Button from 'react-bootstrap/Button';
// import Badge from 'react-bootstrap/Badge';

function App() {
  return (
    <div>
      <p>
        <Button variant="primary">
          Profile <Badge bg="secondary">9</Badge>
          <span className="visually-hidden">unread messages</span>
        </Button>
      </p>
    </div>
  );
}

export default App;

# 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 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 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 react-bootstrap is in your dependencies object

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

Copied!
{
  // ... rest
  "dependencies": {
    "bootstrap": "^5.1.3",
    "react-bootstrap": "^2.2.2",
  },
  // 👇️ only if you use TypeScript
  "devDependencies": {
    "@types/bootstrap": "^5.1.9",
    "@types/react-bootstrap": "^0.32.29",
  }
}

The react-bootstrap 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-bootstrap@latest bootstrap@latest

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