Nativescript-cli: "TypeError: Path must be a string." on npm i -g nativescript

[BeatPots]

Hello to everybody!
I'm a bit frustrated for the NativeScript installation on my Mac OSX Sierra . .

I have read and followed the 'NativeScript Advanced Setup: macOS' on http://docs.nativescript.org/start/ns-setup-os-x#system-requirements.

I have a problem on 'npm i -g nativescript': there is an error after the 'Exec xcodebuild -version' (see the tns doctor log below), 'TypeError: Path must be a string. Received undefined'.

As you have understood, I'm new on NativeScript.

What can I do??
Tnx to everybody!

WARNING: adb from the Android SDK is not installed or is not configured properly.
For Android-related operations, the NativeScript CLI will use a built-in version of adb.
To avoid possible issues with the native Android emulator, Genymotion or connected
Android devices, verify that you have installed the latest Android SDK and
its dependencies as described in http://developer.android.com/sdk/index.html#Requirements

TIP: To avoid setting up the necessary environment variables, you can use the Homebrew package manager to install the Android SDK and its dependencies.

Hi @BeatPots Can you please run

ls $ANDROID_HOME
ls $ANDROID_HOME/platforms

It looks your ANDROID_HOME variable is not set, points to wrong location or AndroidSDK (or some of its components) is not installed.

[BeatPots]

Tank'you dtopuzov!!
You made my day!
My $ANDROID_HOME was totally wrong!
Now I relaunched the command, it's gone OK!

Thank'you so much! :)
