phantomjs cannot find module webpage in node's child process - node.js

Question

I'm trying to run phantomjs in a node child process. Phantomjs complains it can not find module 'webpage'. Running the script from the cli works fine:
phantomjs script.js
I stripped the problem down to these two files:
main.js:
var script = require('./script');
var cp = require('child_process');
cp.exec('/usr/bin/phantomjs script.js');
script.js
var page = require('webpage').create();
page.open("http://www.google.com", function(status) {
console.log("opened google? ", status);
var title = page.evaluate(function(s) {
return s;
}, 'Hello');
console.log(title);
phantom.exit();
});
Running the following command fails:
node main.js
with error:
module.js:340
throw err;
^
Error: Cannot find module 'webpage'
I've tried to specify the working directory in cp.exec as an option without effect. Is there a way to set the node search path for modules in a global context so it can be found in a new node process? Or am I doing something else wrongly?

PhantomJS is not a node.js module and cannot be directly used from node. I think you understand this, because you try to invoke it via child_process.
The problem is the line var script = require('./script');. As I understand, it is the phantomjs script. Since node.js doesn't have a webpage module, but phantomjs does the require fails and everything with it. Simply remove the line. It doesn't seem like you use it anyway.
