Crosswalk installation for ionic fail

I'm trying to install crosswalk for ionic framework through the official ionic site:

Crosswalk installation

After running ionic browser add crosswalk at cmd I get the following warning/error repeating about 15 times

Fetching Android SDK API 19.1.0 Had an error fetching the Android SDK required for Crosswalk. (CLI v1.3.7)

I've already downloaded the required SDK through the eclipse SDK manager but I keep getting the error.

I'm adding some relevant outputs:

ionic --version: 1.3.7

cordova --version: 4.2.0

node --version: v0.10.36

npm --version: 1.4.28

nvm --version: version 1.0.6

Could you please open Android SDK Manager to check if 19.1 is installed? BTW, for Crosswalk later than 11.40.271.0, please use Android SDK API level 21: android-21

I had to add ~/Library/Android/sdk/tools/ to my path on OSX.
