Set locale for moment js with different version

[grkov90]

Chart.js/src/scales/scale.time.js

Line 5 in be6660c

moment = typeof moment === 'function' ? moment : window.moment;

Hello ! )

Project structure:

 app/
    main.js
    /node_modules
      /moment — version 2.19
      /chart.js
        /node_modules
          /moment — version 2.18

Simple code. But not work.

// main.js
import 'moment';
import 'moment/locale/ru';
moment.locale('ru');

'scale.time.js' from Chart.js works with 'en' locale.

scale.time.js have self 'moment' instance, different from app 'moment' instance.

global variables is evil

I think need write:

moment = window.moment || moment ;
if (!moment) throw new Error...
