title: Cannot find module node.js
body: <p>I created a new folder on my desktop and in that folder I put a file named app.js containing the following code.</p>
  
  <pre><code>function sayHello(name) {
      console.log("Hello" + name);
  }
  
  sayHello("Noah")
  </code></pre>
  
  <p>In the terminal I entered node app.js and was returned the following.</p>
  
  <pre><code>module.js:549
  throw err;
  ^

  <p>I followed a Digital Ocean tutorial to get everything installed and everything worked as described. Am I putting my files in the wrong location? </p>
