[Packager] Requiring momentjs locale fails

I’m trying to use a different locale for Moment.js, and I keep receiving the same error. This is the code:

var moment = moment();
moment.locale('es');

And I’m receiving this error in the Chrome Dev Tools console:

Error: Requiring unknown module "./locale/es". If you are sure the module is there, try restarting the packager.
 stack: 
  Object.ErrorUtils.applyWithGuard  index.ios.bundle:880

  eval                              eval at evaluate …:1

It doesn’t seems a Moment.js error though.

@alvaromb - just a quick thought from browsing the moment docs, what about:

var moment = require('moment');
var esLocale = require('moment/locale/es');
moment.locale('es', esLocale);

@brentvatne loading the locale directly i.e require('moment/locale/es'); works. I’m trying to set the locale dynamically, AKA, I get the locale from user device and then load the specific locale.

const deviceLocale = React.NativeModules.RNI18n.locale;
// fails
require('moment/locale/' + deviceLocale); 

Is there other way to solve it besides:

switch deviceLocale:
case 'es':
  require('moment/locale/es');
case 'he':
  require('moment/locale/he');
