can't launch nodemon

[j0hn]

I can't run nodemon on the simplest node.js app, i get this error:

$ nodemon main.js
17 Dec 16:29:11 - [nodemon] v0.5.7
17 Dec 16:29:11 - [nodemon] watching: /media/Datos/j0hn/Code/js/node/simple

node.js:201
        throw e; // process.nextTick error, or 'error' event on first tick
              ^

    at EventEmitter._tickCallback (node.js:192:40)
zsh: exit 1     nodemon main.js
$

the content of main.js it's just:

var http = require("http");

var server = http.createServer(function(req, res){
    res.writeHead(200);
    res.end("hhelllaskd asdi o");

});

server.listen(8080);

My version of node it's 0.6.6 and the version of nodemon 0.5.7 and i've installed nodemon from npm.

Any clue on how to get this working?

When nodemon runs it creates a file called .monitor - it might be that it doesn't have permission to write this file perhaps? Can you check permissions.

oh, i was working on a NTFS partition, I've moved the files to a ext-4 file system and worked. That was it.
