title: Cannot find module 'browserify'
body: <p>I'm getting this error:</p>
  
  <blockquote>
    <p>Error: Cannot find module 'browserify'</p>
  </blockquote>
  
  <p>When I add this line to my app/server.js file:</p>
  
  <pre><code>var browserify = require('browserify');
  </code></pre>
  
  <p>Now I'm still new to Node, but I think I installed it correctly, via</p>
  
  <pre><code>npm install -g browserify
  </code></pre>
  
  <p>as per <a href="https://github.com/substack/node-browserify#install" rel="noreferrer">their docs</a>.</p>
  
  <p>I'm pretty sure this is the command to check my global modules:</p>
  
  <pre><code>D:\Websites\MySite&gt; npm ls -g
  C:\Users\Mark\AppData\Roaming\npm
  ├─┬ browserify@1.17.2
  │ ├─┬ buffer-browserify@0.0.4
  │ │ └── base64-js@0.0.2
  </code></pre>
  
  <p>It lists browserify there. So why can't I <code>require</code> it?</p>
