Cannot find module 'mongoose' error in Node.js #

To solve the error "Cannot find module 'mongoose'", make sure to install the mongoose package by opening your terminal in your project's root directory and running the following command: npm i mongoose and restart your IDE and development server.

cannot find module mongoose

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

shell
npm install mongoose

This will add the mongoose package to the dependencies of your project.

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 "Cannot find module 'mongoose'" error, open your package.json file and make sure it contains the mongoose package in the dependencies object.

package.json
{ // ... rest "dependencies": { "mongoose": "^6.2.8", } }

You can try to manually add the line and re-run npm install.

shell
npm install

Or install the latest version of the package:

shell
npm install mongoose@latest

The mongoose 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.

To solve the error "Cannot find module 'mongoose'", make sure to install the mongoose package by opening your terminal in your project's root directory and running the following command: npm i mongoose and restart your IDE and development server.
