title: Why did I got the ENOENT?
body: <p>File <code>target.txt</code> and <code>watcher.js</code> is in the same directory <code>nodeex</code>. What is incorrect? </p>
  
  <pre><code>node --harmony nodeex/watcher.js
  </code></pre>
  
  <p>This is file <code>watcher.js</code></p>
  
  <pre><code>const fs = require('fs');
  fs.watch('target.txt', function() {
    console.log("File 'target.txt' just changed!");
  });
  console.log("Now watching target.txt for changes...");
  </code></pre>
