Trying to use the mathjs module for some matrix maths in NodeJS. The require statement seems to throw an exception
var math = require("mathjs");
Exception is:

This must be something simple. Any ideas gratefully received?

Was hoping to see if anyone knows why this error is occurring? I am trying to deploy an app to digital ocean and everything was going well until this.

Where /myapp/bin/www:11:5 refers to the following line:
var app = require('../app')
app.set('port', process.env.PORT || 3000); // <- this line
^
The app works well, so it's not related to the app setup.
Any idea?
First guess is you have a circular dependency, which node handles by returning an empty object until the circle is finished. Do you do something like require("./bin/www"); inside app.js?
If you post app.js and bin/www we should be able to confirm.
Second guess is app.js just isn't getting the commonjs exports correct.
I'm also pretty sure you should be able to test your express app with supertest loading just app.js and leaving bin/www just for when you launch a real server instance.
When i try to start my app i see the following error. How can i fix it?
