Error cannot find module mongoose

Looks like you’re having trouble with the “Cannot find module ‘mongoose’” error in NodeJS. To get around this issue, you need to install the mongoose package before using it. Check out the information below for the solution.

Why does this error occur in your project?

The leading cause of this error is most likely because you have not installed the package ‘mongoose’ in your project.

Mongoose is a JavaScript framework commonly used in Node.js applications with the database as MongoDB. However, it is not built-in when you initialize a NodeJS project. That’s why you need to install the mongoose package before using it to avoid getting the error message “Cannot find module ‘mongoose’”.

Solved – “Cannot find module ‘mongoose’” error in NodeJS

You must install the mongoose package to get around this error in NodeJS. To do this, open the terminal at the root of your project and execute the command below:

::install the mongoose package
npm install mongoose

::if you want to install the latest version
npm install [email protected]

After executing the above command, ‘mongoose’ will be added to your project’s dependencies.

Open the package.json file and check. You should now see the dependencies object containing ‘mongoose’ as shown below:

{
  "dependencies": {
    "mongoose": "^6.8.0",
    //...other settings
  }
  //...other settings
}

If your package.json file does not contain the ‘mongoose’ package like in the example above, your installation has failed.

Now you can manually fill in the object dependencies with the line: ‘mongoose’: #version (replace #version with the version you want to install), then run this command:

npm install

After the installation, we recommend you restart the IDE to ensure your project is up to date with the latest changes.

If the error persists, try removing the ‘node_modules’ folder and ‘package_lock.json’ file in your project, then execute the ‘npm-install’ command again:

rm -rf node_modules
rm -f package-lock.json
npm install

At this point, the error seems to have been solved. You can already start working with the ‘mongoose’ package in your project without worrying about the error.:

// Import if you get error when use `require()` syntax
import { createRequire } from 'module';
const require = createRequire(import.meta.url);
// Use the Node.js `require()`
const mongoose = require('mongoose');
console.log(mongoose.version);

// Use the ES6 imports
import mongoose from 'mongoose';
console.log(mongoose.version);

Conclusion

To sum up, we just shared with you the solution for the “Cannot find module ‘mongoose’” error in Node.js. You must install the ‘mongoose’ package before using it to get rid of this problem. That’s the end of this post. Hopefully, the information we provide will be helpful to you.
