In today’s post, we will learn how to resolve the Cannot find module error in Node.js.

the package.json File

Before diving into the solution, we will first try understanding the package.json file and why it is needed.

The package.json file is any Node project’s root or heart. This file records all the important metadata information about a project that is required before publishing it in npm.

It also defines the functional attributes of a project that uses npm to install dependencies, run scripts, and determine the entry point to our package.

npm is the world’s largest software registry. Open source developers on every continent use npm to share and borrow packages, and many organizations also use npm to manage private developments.

Resolve the Cannot find module Error in Node.js

The Cannot find module error occurs when the module is not installed globally. It’s a problem with the script or the npm application.

Follow one of the solutions below to fix the problem:

1. Try to install the module in the local application folder first. Make sure you have the latest version of the module which you are trying to install by running the command:

   $npm install module-name
   

2. Bind the existing global module to your local application. If the above solution doesn’t work, try binding a globally installed module to your application.

   In your application, open the terminal and run the following command:

   $npm link module
   

3. Delete the below files/folders from your local application.

   • the package-lock.json file (not the package.json file)
   • the /node_modules folder or run the rm -rf node_modules command in the terminal

Once the above files/folders have been deleted, install the packages again by running:

$npm install

This will install all the packages with the latest version.
