Install Calabash-Android causes error on OS X Mavericks

I need some help with trying to install Calabash-Android. After installing rvm, home-brew, when I install Calabash i get a strange error:

sudo gem install calabash-android
Building native extensions.  This could take a while...

Not sure what the error means, I have installed Xcode tools for mavericks as well. Any thoughts out there?

Answer 1

I had the same problem and I just found out a solution for this.

I found one related problem here:

http://techespanto.wordpress.com/2013/03/29/upgrade-ruby-version-on-mac-osx/

and it suggested I had to upgrade the ruby version on my machine. The first two commands in that link are not working, so I leave you here what I did:

Install the command line tools for mac with:

xcode-select --install

Install homebrew in your mac with:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

Install rvm with:

\curl -L https://get.rvm.io | bash -s stable --rails --autolibs=enable

List the latest ruby versions with:

rvm list known

Install the latest ruby version with:

rvm install ruby-<version>

(for me it was ruby-2.1-head)

And that's all. Hope it works for you as well!
