title: Node js. Cannot find module 'cache'
body: <p>My index.js file requires module cache.
  I have installed it using npm but the error doesnt go away.</p>
  
  <pre><code>var cache = require('cache')({
  backend: 'memory'
  });
  </code></pre>
  
  <p>After this didnt work i installed it using -g option as well but the error persisted.
  Any thoughts?</p>
