Angular4.x Module not found: Error: Can't resolve 'classlist.js' : <p>When I remove comment part in polyfills.ts for polyfills to load page in Internet Explore</p>

</p>

<p>But if we do build using angular cli. it throws error in console
I did run this command in project "npm install --save classlist.js"</p>

<pre><code>Module not found: Error: Can't resolve 'classlist.js' in src
 @ ./src/polyfills.ts 36:0-22
 @ multi ./src/polyfills.ts
</code></pre>

<p>Please suggest solution</p>
