I have managed to figure this out.

[robertleeplummerjr]

What was the issue?

[TheTrueGravity]

It is an issue with gl. I thought I had it sorted out but it is now not working again. I have decided to ask the creators of gl instead so they know that if there is an issue,and so they are able to sort it out and publish a fix for it.

We have a similar issue here: https://github.com/BrainJS/brain.js/issues/655

[TheTrueGravity]

I have asked the people over at gl and they have said that it is possibly an issue with not having the correct dlls for 32 bit. I am guessing that this is the case for me because I have x86 node js installed. I am now awaiting an answer.

[TheTrueGravity]

I have fixed this by installing an x64 version of node js!

[robertleeplummerjr]

(yes!)
