"Module not found: Can't resolve 'firebase'" #

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

module not found cant resolve firebase

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

shell
# 👇️ with NPM npm install firebase # ---------------------------------------------- # 👇️ with YARN yarn add firebase

The command will add the firebase package to the dependencies of your project.

Make sure to restart your development server and your IDE if necessary. Your dev server won't pick up the changes until you stop it and re-run the npm start command.

You should now be able to import and use the firebase package in your application.

App.js
import { initializeApp } from 'firebase/app'; // TODO: Replace the following with your app's Firebase project configuration const firebaseConfig = { //... }; const app = initializeApp(firebaseConfig);

For more information refer to the npm page of the firebase module.

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.

shell
# 👇️ 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
Make sure to restart your IDE and dev server if the error persists. VSCode often glitches and a reboot solves things sometimes.

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

package.json
{ // ... rest "dependencies": { "firebase": "^9.6.10", }, }

The firebase 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.

shell
npm install

Or install the latest version of the package:

shell
npm install firebase@latest
