Can't load module in Node console using symlinks

I'm on cygwin to do unix commands on win7 (launched cygwin.bat in windows cmd prompt).

My project directories are created in root like this:

$ mkdir -p app/models
$ mkdir -p app/node_modules

Then the symlink is created:

$ cd app/node_modules
$ ln -sf ../models

Back on the /app/ directory, I go into Node console to launch the module located in app/models/movie.js:

Movie = require('models/movie');

But I get the following error:

Cannot find module 'models/movie'

ln takes 2 arguments, not one.

I found out that cygwin doesn't really create actual symlinks by default. I had to create native NTFS symlinks using export CYGWIN="winsymlinks:native"
