Read tags from JPG using Exiftool and NodeJS

Question

I am trying to get the tag metadata from a JPG image using NodeJS and the exiftool. This is the first time I am using NodeJS. This is what I tried: I installed NodeJS for windows. I have an image with the name t.jpg and in the same directory I have a js file called run.js

This is the run.js file

var exif = require('exiftool');
var fs   = require('fs');
fs.readFile('t.jpg', function (err, data) {
    if (err) {
        console.log(err);
    } else {
        exif.metadata(data, function (err, metadata) {
            if(err)
                console.log(err);
            else
                console.log(metadata);
        });
    }
});

I then opened a command line window and typed the following:

I assumed I needed to add whatever was required in the code

npm install exiftool
npm install fs
node run.js

I then got the following error:

> node run.js
events.js:160
  throw er; // Unhandled 'error' event
  ^

Error: write EPIPE

Any idea what am I doing wrong? What can I do to get what I want?

See comments -> exiftool must be installed in system PATH. To easily test this, try running exiftool from command line (cmd or powershell).
