Node js and phantomjs - Cannot find module 'weak'

I am running on Linux Mint 16 'petra' 64 bit, and I am trying to use 'phantomjs' for the first time, together with node js.

I have installed phantomjs globally:

sudo npm install -g phantomjs

... and confirmed that it is running (I get the phantomjs prompt by running "phantomjs" in terminal)

and I have installed the node 'phantom' module within my node project:

npm install phantom

So far so good.

However, within my application code, as soon as it attempts to execute this line:

var phantom = require('phantom');

... the program crashes with the following trace:

Listening on port 3000
about to instantiate phantom module...
module.js:333
    throw err;
          ^

I can confirm that indeed there is no 'weak.js' anywhere in the project.

I have run 'npm install' to ensure that all dependencies have been installed.

Google search hasn't revealed anything worthwhile. Can anyone offer any advice?

I had the same issue using node.js and phantom in a windows machine, what I found that you need some special treatment on the windows enviroment. the npm document is here.

var phantom = require('phantom');
phantom.create(function(ph) {
    return ph.createPage(function(page) {
      return page.open("http://www.google.com", function(status) {
         console.log("opened google? ", status);
         return page.evaluate((function() {
            return document.title;
      }), function(result) {
        console.log('Page title is ' + result);
        return ph.exit();
      });
    });
  });
}, {
    dnodeOpts: {weak: false}
});

notice phantom.create(function, options, callback), and here options uses dnodeOpts: {weak: false}
