How can I make stellarjs work with webpack?

Question

I'm using webpack to handle my js task. Now I import stellajs in my main script by this:

import $ from 'jquery';

require('imports?define=>false!./jquery.stellar');

Or

import $ from 'jquery';

import './jquery.stellar';

But I always got

Uncaught TypeError: (0 , _jquery2.default)(...).stellar is not a function

How can I use jquery stella in webpack. Thank you!
