Install capybara-webkit on Mavericks

I got a brand new Mac Air recently, when I tried to install
capybara-webkit I encountered some problems.

The Error

Got this error when bundle install one rails app.

Installing capybara-webkit (0.12.1)
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

An error occurred 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.

Tried brew install qt didn’t get luck, raised this error:

Checked all those links and tried several things, eventually downloading
qt installer from the qt-project website solved my problem.

Download link

Just install the debug libraries, qt libraries then bundle install


If you already got qt installed and capybara-webkit worked before
upgrade to Mavericks, then it’s probably gonna work as well.
