具有Moment TimeZones的Ionic 2 Moment JS

Question

I'm working on using moment.js with typescript . I ran the following commands

npm install moment-timezone --save
npm install @types/moment @types/moment-timezone --save

but for some reason in the formattime function, moment is undefined. I'm not getting any errors from my IDE regarding my import of moment and I can see both moment and moment-timezone are in the npm folder. I've been crawling through post but I'm not seeing much helpful information. Any help would be greatly appreciated

import moment from 'moment';

export class Utils {

    text: string;

    constructor() {
        console.log('Hello Utils Component');
    }


    //This function take the time in MS and the timezone and coverts it
    //@params time - time in milliseconds
    //@params tz - the timezone
    //@paramz isZoneAbbr - true if the zone abbr should be displayed
    //@return - return formattedTime
    public formatTime(time, tz, isZoneAbbr): string {
        console.log(JSON.stringify(moment));
        return "";
        // var formattedTime = moment.tz(time, tz);
        // if (isZoneAbbr) {
        //     return formattedTime.format('h:mm a z');
        // }
        // return formattedTime.format('h:mm a');
    };
}

您可能必须引用的是moment-timezone而不是moment因为它不是moment包

import * as momentTz from 'moment-timezone';
