Incompatibility with create-react-app

How does one use Globalize and the DateTimePicker from react-widgets with [create-react-app](https://github.com/facebook/create-react-app)?

From an empty project:
```
npx create-react-app
```

my package.json
```
{
"name": "test-globalize",
"version": "0.1.0",
"private": true,
"dependencies": {
"cldr-data": "latest",
"globalize": "^1.3.0",
"iana-tz-data": ">=2017.0.0",
"react": "^16.2.0",
"react-dom": "^16.2.0",
"react-scripts": "1.1.1",
"react-widgets-globalize": "^5.0.0"
},
"cldr-data-urls-filter": "(core|dates|numbers|units)",
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject"
}
}
```

my index.js
```
import React from 'react';
import ReactDOM from 'react-dom';
import Globalize from 'globalize';
import globalizeLocalizer from 'react-widgets-globalize';

import './index.css';
import App from './App';
import registerServiceWorker from './registerServiceWorker';

Globalize.locale('en');

globalizeLocalizer();

ReactDOM.render(, document.getElementById('root'));
registerServiceWorker();
```

Produces the errror:
```
Failed to compile.

./node_modules/globalize/dist/globalize.js
Module not found: Can't resolve 'cldr' in '/Users/jd/sandbox/test-globalize/node_modules/globalize/dist'
```

For some reason globalize will not compile, and index.js doesn't get run. Is there a fix without ejecting?
