I want to install Calabash Android on Ubuntu(13.10). I have gem (1.8.23) and ruby (1.9.3p194) installed and tried to run "sudo gem install calabash-android" but keep getting messages saying "Failed to build gem native extension", below is the full messages:

Building native extensions. This could take a while... ERROR: Error installing calabash-android: ERROR: Failed to build gem native extension.

    /usr/bin/ruby1.9.1 extconf.rb

/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in require': cannot load such file -- mkmf (LoadError) from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:inrequire' from extconf.rb:1:in `'

Gem files will remain installed in /var/lib/gems/1.9.1/gems/gherkin-2.12.2 for inspection.

I tried "sudo apt-get update" but it didn't fix the issue. And I also checked gcc so it shouldn't be build issue. Does anyone have any suggestions? Thanks in advance!

While installing ruby, select development version or full version, so on my system with ubuntu 12.04, i would use 

sudo apt-get install ruby1.9.1-full

also please make sure android home path and ant path is proper

Thanks

You can use rbenv that manage perfectly ruby gems versions like nvm does for node.js:

$ sudo apt-get update
$ sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev
$ git clone git://github.com/sstephenson/rbenv.git .rbenv
$ echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
$ echo 'eval "$(rbenv init -)"' >> ~/.bashrc
$ git clone git://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
$ echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
$ git clone https://github.com/sstephenson/rbenv-gem-rehash.git ~/.rbenv/plugins/rbenv-gem-rehash
$ sudo apt-get install rbenv
$ exec $SHELL
$ rbenv install 2.2.2
$ rbenv global 2.2.2
$ ruby -v
$ echo "gem: --no-ri --no-rdoc" > ~/.gemrc
$ gem install bundler
