Node dependencies not found when ran programatically

Question

UPDATE: There seems to be an issue with the cylon.js library. https://github.com/hybridgroup/cylon/issues/277

I am working on my first Node project and have run into some small issues with dependencies.

If I execute my server.js using node server.js, everything works as expected, all my deps are in the correct place and read just fine.

However, if I attempt to use init.d scripts to call it, or attempt to call it from within a different node program, I get errors that some of my dependencies are not found. It suggests using npm to reinstall them, and I have added the npm install line to the script just to make sure, but that has not had any effect.

I, [2015-06-29T17:29:12.661Z] INFO -- : [ardrobot] - Initializing connections.

Cannot find the 'cylon-intel-iot' module. This problem might be fixed by installing it with 'npm install cylon-intel-iot' and trying again.

    'use strict';

    var wait = require('wait.for')
    var Cylon = require('cylon');
