“moment” has no exported member ‘default’ when importing the library.

在material中的时间控件中，使用moment.js来更改本地日期格式时，出现如下错误：

"moment" has no exported member 'default' when importing the library.

1	"moment" has no exported member 'default' when importing the library.

下面是我的代码：

import {Inject, Injectable, Optional} from '@angular/core';
import {DateAdapter, MAT_DATE_LOCALE, MatDateFormats} from '@angular/material';
import * as _moment from 'moment';
import {default as _rollupMoment, Moment} from 'moment';

const moment = _rollupMoment || _moment;

import {Inject, Injectable, Optional} from '@angular/core';

import {DateAdapter, MAT_DATE_LOCALE, MatDateFormats} from '@angular/material';

import * as _moment from 'moment';

import {default as _rollupMoment, Moment} from 'moment';

const moment = _rollupMoment || _moment;

angular中 *ngFor得到index

<ul>
    <li *ngFor="let item of items; let i = index">     
       {{item}}
    <i (click)="deleteThis(i)">x</i>
    </li>
</ul>

<ul>

</li>

</ul>

上面代码的

let i = index

1	let i = index

即可获得index
