"moment" has no exported member 'default'

Question

I'm using moment.js to change the local date format for my application but getting the following error:

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

Below is my code:

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;

Answer 1

Try adding "allowSyntheticDefaultImports": true to your tsconfig.json under the "compilerOptions"

Answer 2

You seems to have trouble importing moment

As you can see in the documentation, For Typescript 2.x try adding "moduleResolution": "node" in compilerOptions in your tsconfig.json file and then use any of the below syntax:

import * as moment from 'moment';
import moment = require('moment');

PS: Make sure you have installed moment.js with npm:

npm install --save moment
