title: How to use node modules from command line?
body: <p>I can't find any straightforward instructions on this. I've installed node.js and npm, then created a project in its own folder, <code>D:\node_stuff</code>, then cd'd there via <code>cmd</code> (Windows 10) and ran <code>npm install express</code>, <code>npm init</code>. I'm trying to use <a href="https://github.com/vvo/gifify" rel="nofollow noreferrer">gifify</a>, and installed its dependencies via <code>npm</code> instead of <code>brew</code> (ffmpeg, imagemagick, giflossy).</p>
  <ul>
  <li><code>gifify -h</code> -&gt; 'gifify' is not recognized as an internal or external command,
  operable program or batch file.</li>
  <li><code>node gifify -h</code> -&gt; Error: Cannot find module 'D:\node_stuff\gifify'</li>
  <li><code>cd node_modules</code> -&gt; <code>node gifify -h</code> -&gt; nothing happens</li>
  </ul>
  <p>What am I doing wrong? Where do I even look - all tutorials with simple search only show how to install packages or build a project - I don't need to build anything, only to use this one module.</p>
