primordials is not defined during npm install

I just tried installing `royale-js-swf` with
```
npm install @apache-royale/royale-js-swf -g
```
and I got the following:-
```
$ npm install @apache-royale/royale-js-swf -g
npm WARN deprecated graceful-fs@3.0.11: please upgrade to graceful-fs 4 for compatibility with current and future versions of Node.js
npm WARN deprecated natives@1.1.6: This module relies on Node.js's internals and will break at some point. Do not use it, and update to graceful-fs@4.x.
