Question

I can install capybara-webkit on Mac, when I deployed code on Ubuntu, I am facing below error

    Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

            /usr/local/bin/ruby extconf.rb 


    Gem files will remain installed in /home/datas/.bundler/tmp/7940/gems/capybara-webkit-0.12.1 for inspection.
    Results logged to /home/datas/.bundler/tmp/7940/gems/capybara-webkit-0.12.1/./gem_make.out

   An error occured while installing capybara-webkit (0.12.1), and Bundler cannot continue.
   Make sure that `gem install capybara-webkit -v '0.12.1'` succeeds before bundling.

Even I tried with sudo gem install capybara-webkit -v '0.12.1'

I am getting same error.
