Error from rollup when importing moment.js with rc0

Ionic Framework ionic-v3
1

I get have a project where use moment.js and imports moment.js using the recommended import syntax

import * as moment from "moment";

This worked fine in beta-11 but now in rc0 with rollup as part of the build process I get the following error when running ionic serve

[21:14:48]  bundle dev started ...
[21:14:54]  Error: Cannot call a namespace ('moment')

Any help resolving this issue would be greatly appreciated.

Had the same, changed it to:

Import moment from ‘moment’

Thanks so much @fishgrind! That was exactly the problem.

Also, I was using import Moment from 'moment' instead of import moment from 'moment' and the compiler had issues with the capital letter. Keep it lower case and it should work.

It is neat being able to import moment just the way we import other modules, don’t you think? :slight_smile:

I’ve tried this and am still getting the console error:

Error: Cannot call a namespace ('moment')

Anything else you did?
