Module not found: Can't resolve 'react-transition-group'

Module not found: Can't resolve 'react-transition-group' #

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

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

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

# 👇️ with YARN
yarn add react-transition-group

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

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

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

Copied!
# 👇️ delete node_modules and package-lock.json
rm -rf node_modules
rm -f package-lock.json

# 👇️ clean npm cache
npm cache clean --force

npm install

If you're still getting the "Module not found: Error: Can't resolve 'react-transition-group'" error, open your package.json file and make sure it contains the react-transition-group package in the dependencies object.

Copied!
{
  // ... rest
  "dependencies": {
    "react-transition-group": "^4.4.2",
  },
  "devDependencies": {
    "@types/react-transition-group": "^4.4.4",
  }
}

The react-transition-group 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-transition-group@latest

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