Error using moment.js with alpha46 Ionic 2

Ionic Framework ionic-v3
6

So this import uses the default import and put it in the moment_var variable

import moment_var from ‘moment’;

This one searchs for an export named moment and imports it like that

import {moment} from ‘moment’;

And this one does the same as above but rename the variable to moment_var

import {moment} as moment_var from ‘moment’;

That’s as i understand the use cases of the import/export so far.
