After forking & cloning the google / material-design-lite, I cannot get the local project to work

I would like to contribute by creating a dark mode for **mdl lite**

After forking & cloning the `google / material-design-lite`, I then use:

`npm install`

I then install:

```
npm install -g gulp-cli
npm install -g babel-register
```

But, when I go:

`gulp serve`

I get:

```
Requiring external module babel-register
ReferenceError: primordials is not defined
```

I am using Windows 10...
