phonegap platform add ios - "Unexpected token =>" error

I have a Phonegap app and need to build it in a Mac. Everything works in a machine and I'm trying to configure a new one, but on this, when I run phonegap platform add ios I receive the following error:

$ phonegap platform add ios
/usr/local/lib/node_modules/phonegap/lib/phonegap/util/connect-proxy.js:21
                fs.readFile(settings, (err, data) => {
                                                  ^^

Both Macs are running with node v0.12.7 and npm 2.11.3.
