Apparently you’re executing the command npm start at wrong location... you are running inside the installation folder on NodeJs.

You should create a folder for your project and add the file to it .js execution of your application. To use the command npm start there should be in your folder a file package json. with the instructions to load "scripts" example:

index js.

// um simples console
console.log('Hello World!')

package json.

{
   "name": "nome-de-sua-aplicação",
   "main": "index.js",
   "version": "1.0.0",
   "scripts": {
       "start": "index"
   }
}

Note that the file package json. may contain a lot of information being in this example when using npm start will execute the file within the instruction scripts.start through this command it is also possible to add optional arguments.

Note: the above example suggests to use inside directories common to the user (desktop, documents, etc...) however its log error reports lack of administrative privileges as it was running inside folders commonly protected by the operating system.

You can execute commands NodeJs even inside bad system protected folders if this is the case should start the prompt command (CMD) with administrator privileges.
