Module not found: Can't resolve 'firebase' [Solved]

# "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

Copied!
# 👇️ with NPM
npm install firebase

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

# 👇️ with YARN
yarn add firebase

install firebase module

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

Copied!
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.

# 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.

shell

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.

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 `firebase` in your `dependencies` object

If you're still getting the error, open your package.json file and make sure it contains the firebase package in the dependencies object.

package.json

Copied!
{
  // ... 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.
