How to fix the npm WARN unmet dependency Error

In this tutorial, we are going to learn about how to fix the npm WARN unmet dependencies error in our node project.

When we run an npm install command in our project, sometimes the following error is printed in our terminal.

npm WARN unmet dependency  /Users/sai/my-app/node_modules/lab requires handlebars@'2.x.x' but will load
npm WARN unmet dependency /Users/sai/my-app/node_modules/handlebars,
npm WARN unmet dependency which is version 3.0.0
npm WARN unmet dependency /Users/sai/my-app/node_modules/gulp/node_modules/vinyl-fs/node_modules/glob-watcher/node_modules/gaze/node_modules/globule/node_modules/glob requires graceful-fs@'~1.2.0' but will load
npm WARN unmet dependency /Users/sai/my-app/node_modules/gulp/node_modules/vinyl-fs/node_modules/graceful-fs,
npm WARN unmet dependency which is version 3.0.6

This error occurs when a node_modules folder is corrupted in your project. Due to the network interruption or other reasons, to fix this follow the below steps.

1. First, remove the node_modules folder present inside your project directory by using the below command.

rm-rf node_modules

or you can remove it manually by right-clicking on it and select the delete option.

2. Clear the npm cache.

npm clean cache --force

3. Re-install the node modules again by running the npm install command.
