title: Angular - 'Could not find HammerJS'
body: <p>I'm working on a simple angular project where I am trying to import Material Design into my project but some of the components aren't working properly and a console warning says:</p>
  <blockquote>
  <p><strong>Could not find HammerJS. Certain Angular Material components may not work correctly.</strong></p>
  </blockquote>
  <p>I have <code>hammerjs</code> installed and also <code>@angular/material</code>. How do I resolve this issue?</p>

  <h2>Sidenote</h2>
  <p>It may be worth noting that if you have <code>hammerjs</code> installed and your components are still not rendering correctly to make sure you are using <code>angular material</code> <strong>components</strong> and not html elements with <code>materialize-css</code> <strong>classes</strong>.
  If you <em>are</em> using <a href="http://materializecss.com/" rel="noreferrer"><code>materialize-css</code></a> instead of <a href="https://github.com/angular/material2" rel="noreferrer"><code>angular material</code></a>, <a href="http://materializecss.com/getting-started.html" rel="noreferrer">you will need to add it to your project separately. </a></p>
