title: Download system-polyfills.js through npm
body: <p>I want to download some polyfills for the Microsoft internet explorer browser:</p>
  
  <pre><code>&lt;script src="node_modules/es6-shim/es6-shim.min.js"&gt;&lt;/script&gt;
  &lt;script src="node_modules/systemjs/dist/system-polyfills.js"&gt;&lt;/script&gt;
  &lt;script src="node_modules/angular2/es6/dev/src/testing/shims_for_IE.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>I have succeeded to download <code>es6-shim.min.js</code> and <code>shims_for_IE.js</code> through the next commands:</p>
  
  <pre><code>npm install es6-shim
  npm install angular2
  </code></pre>
  
  <p>but I wasn't able to download <code>system-polyfills.js</code> in the same way.
  How can I find this file?</p>
  
  <p>Thanks in advance</p>
