Module not found: Can't resolve 'moment' error #

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

module not found cant resolve moment

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 moment # 👇️ ONLY If you use TypeScript npm install --save-dev @types/moment # ---------------------------------------------- # 👇️ with YARN yarn add moment # 👇️ ONLY If you use TypeScript yarn add @types/moment --dev

The command will add the moment 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 moment package in your application.

App.js
import moment from 'moment'; // const moment = require('moment'); // 👈️ CommonJS console.log(moment().format());

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 'moment'" error, open your package.json file and make sure it contains the moment package in the dependencies object.

package.json
{ // ... rest "dependencies": { "moment": "^2.29.1", }, // 👇️ Only if you use TypeScript "devDependencies": { "@types/moment": "^2.13.0", } }

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

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