Node webkit - unable to fork a child process ( Error: spawn EACCES )

Question

I have a piece of nodejs code ( link ) that is blocking. So, I am trying to run it in child process.

I am using the following code to fork a child process :

    var path = require('path');
    var nodeWebkitPath = path.dirname(process.execPath);
    var childProcess = require('child_process');

    var macEventDetectorChildProcess = childProcess.fork("./node/worker/osxEventsDetector.js",{
        execPath : nodeWebkitPath
    });

Everytime i try to run my app with this code i get an error :

Error: spawn EACCES
    at exports._errnoException (util.js:893:11)

    at Function.Module._load (module.js:332:12)
    at Function.Module.runMain (module.js:483:10)

Reading through some other answers on SO it seemed to be some permission related error but even after changing the permission for my project folder I am getting this error.

Other Details :

1. OS - Mac
2. Node Webkit Version - 0.14.3

Any help / Suggestion to solve this issue would be much appreciated. Thanks in Adavance.

This a system issue. Try to run your application as administrator.

On linux/mac, you can do it with sudo:

sudo node app.js

On windows, start command line as administrator and run the app normally.
