title: NodeJS: Error: Cannot find module 'ytdl-core'
body: <p>I was creating a discord music bot in NodeJS, with discord.js as well, but whenever I run it, I get this error: (the file is not named module.js)</p>
  
  <pre><code>module.js:549
      throw err;
      ^

  <p>At first, I thought it was because I needed to npm install the module like I did with discord.js, but instead I got the same error.</p>
