  1. The uuid module is not installed in the correct project directory.

npm install uuid@9.0.0

If you’re still facing the error, then follow the below steps to resolve it.

  1. Remove the node_modules folder and package-lock.json file, inside your project directory by using the below command.
rm-rf node_modules package-lock.json

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

  1. Clear the npm cache.
npm clean cache --force
  1. Re-install the node modules again by running the npm install command.

Verify now if you’ve installed it correctly or not by opening the package.json file and check for uuid module in the dependencies object.

 "dependencies": {
     //...
    "uuid": "^9.0.0",

    //.. other packages
 }
