Module not found: Error: Cannot resolve module 'bootstrap'

http://v4-alpha.getbootstrap.com/getting-started/download/#npm:

require('bootstrap') will load all of Bootstrap’s jQuery plugins onto the jQuery object.

File:

const bs = require('bootstrap');

Doesn't require. Error thrown:

If this is the same as #20385, #20418 should fix it.
