Cannot find module 'mongoose' error in Node.js

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.

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

Copied!
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.

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

Copied!
{
  // ... rest
  "dependencies": {
    "mongoose": "^6.2.8",
  }
}

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

Copied!
npm install

Or install the latest version of the package:

Copied!
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.
