Ionic 2: Module 'moment' has no exported member 'UnitOfTime'.

[mauricionarcizo]

I updated the ionic-app-scripts to 0.0.42 and on process 'transpile', I got the following error:

[14:21:19] transpile started ...
[14:21:23] typescript: ...nfo/app/node_modules/angular2-moment/difference.pipe.d.ts, line: 4
Module 'moment' has no exported member 'UnitOfTime'.

   L3:  export declare class DifferencePipe implements PipeTransform {
   L4:   | moment.Moment, otherValue: Date | moment.Moment, unit?: moment.UnitOfTime, precision?: boolean): number;

[14:21:23] transpile failed

As we can see, the 'UnitOfTime' is not an exported module from 'moment'. What I can do to solve this?

Angular2-moment version used is 1.0.0-beta.6.

Same issue here. I don't see anywhere in the momentjs documentation where 'UnitOfTime' exists.

As a workaround until it gets fixed, I added class UnitOfTime {} inside of declare namespace moment {} in the file moment.d.ts, in the moment folder. With this, the project at least compiles.

But I think that this has more to do with momentjs than with this module.

I confirm that angular2-moment currently produces this error with moment 2.16.0. This is the specific commit that introduced that change: moment/moment@8c0c6a3

I hope to publish a new release that will address it within the next few days. In the meanwhile, you can stick with moment 2.15.2

Work!
@urish thanks!

Just wanted to let others know what solution worked for me--I did not revert to the older version of moment -- I am using 2.17.1. Also I didn't need to change any typings files at all.

What I did, in my angular component .ts file was to cast my string variable into the moment

some.component.ts

let convertedChartPeriod: moment.unitOfTime.StartOf = <moment.unitOfTime.StartOf>this.chartPeriod;

var reportStartDate = moment(itemDate).startOf(convertedChartPeriod);

Things of Note:

• proper class name for v2.17.1 is moment.unitOfTime.StartOf
• use the <moment.unitOfTime.StartOf> with the "<>" brackets to cast the string into the proper class.
• No need to change any Damn typings files!

Hi everybody I have this issue: 'moment' has no exported member 'DurationInputArg1'.
Someone knows what happen ? @bitterloa @urish

Complete error:
