Unexpected token export

[Amertz08]

I'm using the babel extension and running into the titled error still.

// In[1]:
%load_ext babel
// In[2]:
%%babel
import { get_base_url, test_successful_resp, test_required_param } from '../testlib';

Given testlib.js

const assert = require('assert');

export const get_base_url = (path) => {
    const base = process.env.DC_API_URL;

    assert.notEqual(base, undefined, 'DC_API_URL not found');
    return `${base}/beta/${path}`;
};
// more functions defined in the same manner

I would think the babel extension would resolve this but I guess I'm not understanding.
