PSP: everything is ok in non-dev mode

after `npm install`, then I run `./bin/kibana --dev --no-ssl --no-base-path`, after I refresh the chrome, I got below error later:

```auto

```

I found some snippet in moment.js source:

```auto
    function loadLocale(name) {
        var oldLocale = null;
        // TODO: Find a better way to register and load all the locales in Node
        if (!locales[name] && (typeof module !== 'undefined') &&
                module && module.exports) {
            try {
                oldLocale = globalLocale._abbr;
                require('./locale/' + name);
                // because defineLocale currently also sets the global locale, we
                // want to undo that for lazy loaded locales
                locale_locales__getSetGlobalLocale(oldLocale);
            } catch (e) { }
        }
        return locales[name];
    }

```

seems kibana use moment.min.js (in moment/min), but there is no `locale` in moment/min, should kibana use `moment-with-locales.min.js` instead?

it seems its a bug? [https://github.com/moment/moment/issues/1435](https://github.com/moment/moment/issues/1435)

Hi @whoami,

Could you tell me which branch and commit SHA of Kibana you are working with? That way I can try to reproduce your error and investigate further.

Thanks,

Shaunak

Hi @whoami,

I just tried to reproduce your issue with the `5.2` branch but was unsuccessful.

I ran `npm ls | grep moment` and got this output:

```auto
├── moment@2.13.0
├── moment-timezone@0.5.4

```

What output do you get if you run the same command?
