angular - "moment"没有导出成员 'default'

Question

我正在使用 moment.js 更改我的应用程序的本地日期格式，但出现以下错误:

"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;

Answer 1

尝试将 "allowSyntheticDefaultImports": true 添加到 "compilerOptions"下的 tsconfig.json
