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'll also need to have the Java Development Kit (JDK) installed and available. Calabash will attempt to automatically find this from registry keys on windows, or monodroid config elsewhere, but you can also specify it explicitly by setting the
JAVA_HOME environment variable to its location (e.g. C:\Program Files\Java\jdk1.8.0_20), or having the JDK binaries themselves (i.e. C:\Program Files\Java\jdk1.8.0_20\bin) in your path.
You should have the Android SDK installed. You can download it from here. Create an environment variable with the name :
ANDROID_HOME and its value pointing to the location of the unzipped downloaded SDK.
You also need to have Ant installed and added to your path. It can be downloaded from here.
calabash-android by running
gem install calabash-android
- You might have to run
sudo gem install calabash-androidif you do not have the right permissions.
If you are on Mac you may see an error like this:
~$ sudo gem install calabash-android Password: Building native extensions. This could take a while... ERROR: Error installing calabash-android: ERROR: Failed to build gem native extension. /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/ruby.h
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.
These instructions assume you'll be using Ruby 1.9.1.
sudo apt-get install ruby1.9.1
You might need to install the dev package when installing calabash:
sudo apt-get install ruby1.9.1-dev
If you see something like this while installing calabash:
cannot load such file -- rspec/expectations (LoadError)
It's because the rspec package isn't installed:
gem install rspec
