You need to have Ruby installed. Verify your installation by running ruby -v in a terminal - it should print "ruby 1.8.7" (or higher).
If you are on Windows you can get Ruby from RubyInstaller.org
You should have the Android SDK installed and the environment variable ANDROID_HOME
should be pointing to it.
You also need to have Ant installed and added to your path
Install calabash-android
by running
gem install calabash-android
- You might have to run
sudo gem install calabash-android
if you do not have the right permissions.
If you are on Mac you may see an error like this:
~$ sudo gem install calabash-android

Building native extensions. This could take a while...

One possible cause can be not having the correct Command Line Tools (compiler tool chain) for your OS X release. For example, for OS X 10.8 "Mountain Lion" you need the "Mountain Lion" version of these. If you have Xcode installed you can install them from it's Preferences pane (in the Download tab). Otherwise you can download the Command Line Tools for you OS X version from the Apple Developer web site.
