Note: If you got the error Module not found: Can't resolve 'reactstrap', click on the second subheading.
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:
# ๐๏ธ with NPM npm install react-bootstrap bootstrap # ๐๏ธ ONLY If you use TypeScript npm install --save-dev @types/react-bootstrap @types/bootstrap # ---------------------------------------------- # ๐๏ธ with YARN yarn add react-bootstrap bootstrap # ๐๏ธ 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.
npm start
command.You should now be able to import and use the react-bootstrap
package in your
React.js app.
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;
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
.
# for macOS and Linux rm -rf node_modules rm -f package-lock.json rm -f yarn.lock # ๐๏ธ clean your npm cache npm cache clean --force # ๐๏ธ install packages npm install
If you are on Windows, issue the following commands in CMD.
# for Windows rd /s /q "node_modules" del package-lock.json del -f yarn.lock # ๐๏ธ clean your npm cache npm cache clean --force # ๐๏ธ 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.
