babel-runtime module not found when using material-ui-pickers

Question

i have a react project built using brunch. I am now trying to use material-ui-pickers, by just trying the very first example:

// Imports
/* eslint-disable */
import MuiPickersUtilsProvider from 'material-ui-pickers/utils/MuiPickersUtilsProvider';
// pick utils
import MomentUtils from 'material-ui-pickers/utils/moment-utils';

And wrapping the whole app:

<MuiPickersUtilsProvider utils={MomentUtils}>
   <App />
</MuiPickersUtilsProvider>

I am having the following error in the console:

Uncaught Error: Cannot find module 'babel-runtime/core-js/object/get-prototype-of' from 'material-ui-pickers/utils/MuiPickersUtilsProvider.js'

My package.json:

{
  "name": "brunch-app",
  "description": "Brunch.io application",
  "private": true,
  "author": "",
  "version": "0.0.1",
  "repository": "",

    "eslint-plugin-react": "^7.6.1",
    "hmr-brunch": "^0.1",
    "uglify-js-brunch": "^2"
  }
}

I haven't found much info, the only thing was about installing babel-runtime, which i did but did not work.

Thanks.
