你需要时间。lang(警告:lang()自2.8.0时刻起已弃用，请使用locale()代替):

moment.lang("de").format('LLL');

http://momentjs.com/docs/#/i18n/

从v2.8.1开始，moment.locale('de')设置本地化，但不返回时刻。一些例子:

var march = moment('2017-03')
console.log(march.format('MMMM')) // 'March'

moment.locale('de') // returns the new locale, in this case 'de'
console.log(march.format('MMMM')) // 'March' still, since the instance was before the locale was set

var deMarch = moment('2017-03')
console.log(deMarch.format('MMMM')) // 'März'

// You can, however, change just the locale of a specific moment
march.locale('es')
console.log(march.format('MMMM')) // 'Marzo'

总而言之，在全局moment上调用locale将为所有未来moment实例设置locale，但不会返回moment实例。在实例上调用locale，为该实例设置它并返回该实例。

此外，正如Shiv在评论中所说，确保你使用的是“moment-with-locale .min.js”而不是“moment.min.js”，否则它将无法工作。

我还必须导入语言:

import moment from 'moment'
import 'moment/locale/es'  // without this line it didn't work
moment.locale('es')

然后像平常一样利用这一刻

console.log(moment(date).fromNow())

2017 / 2018年底:其他答案有太多的旧代码需要编辑，所以这里是我的另一个干净的答案:

与要求

let moment = require('moment');
require('moment/locale/fr.js');
// or if you want to include all locales:
require("moment/min/locales.min");

与进口

import moment from 'moment';
import 'moment/locale/fr';
// or if you want to include all locales:
require("moment/min/locales.min");

Use:

moment.locale('fr');
moment().format('D MMM YY');  // Correct, set default global format 
// moment.locale('fr').format('D MMM YY') //Wrong old versions for global default format

和时区

*要求:

require('moment-range');
require('moment-timezone');

*进口:

import 'moment-range';
import 'moment-timezone';

使用区域:

const newYork    = moment.tz("2014-06-01 12:00", "America/New_York");
const losAngeles = newYork.clone().tz("America/Los_Angeles");
const london     = newYork.clone().tz("Europe/London");

格式化日期的函数

const ISOtoDate = function (dateString, format='') {

 // if date is not string use conversion:
 // value.toLocaleDateString() +' '+ value.toLocaleTimeString();

  if ( !dateString ) {
    return '';
  }

  if (format ) {
    return moment(dateString).format(format);
  } else  {
    return moment(dateString);  // It will use default global format
  }  
};

当我与gulp和朋友一起使用webpack时(这个生成器为我设置了一切)，我不得不对凉亭进行更改。json文件。我必须重写当前包的默认导入，并选择所有语言附带的文件:

"overrides": {
  "moment": {
    "main": [
        "min/moment-with-locales.min.js"
    ]
  }
}

这是我的凉亭。json文件:

根据版本更改moment js语言

版本:2 + 8。

moment.locale('嗨');

版本:2.5.1

moment.lang('嗨');
