Cannot get it to work on Node.js

Today I ran `npm i --save money` and tried to get it to work in my Node.js application:

``` javascript
"use strict";

const fx = require('money');
let converted = fx.convert(1000, {from: "GBP", to: "HKD"});
```

Unfortunately, all I get is this:

``` bash
node_modules\money\money.js:78
        if ( !rates[to] || !rates[from] ) throw "fx error";
```
