Ionic Emulate IOS Fault

I have just follow the instructions on ionic getting started and i am getting this error.

Umuts-MacBook-Pro:myApp umutguncan$ ionic emulate ios

add to body class: platform-ios
Running command: /Users/umutguncan/myApp/platforms/ios/cordova/run --emulator
ios-sim was not found. Please download, build and install version 3.0.0 or greater from into your path. Or 'npm install -g ios-sim' using node.js:

Ionic Info throws this:

Dependency warning - for the CLI to run correctly,
it is highly suggested to install/upgrade the following:

Install ios-sim to deploy iOS applications. npm install -g ios-sim (may require sudo)
Install ios-deploy to deploy iOS applications to devices. npm install -g ios-deploy (may require sudo)

Info says ios-sim not installed, though I have run npm install -g ios-sim and also locally by npm install ios-sim
