Error installing capybara 0.8.0 on Windows 7
===

I'm quite new using Ruby and I need to install a rails server on Windows 7 in order to test few application in IE.

I did everything good (I hope) but now when I try to run `bundle install` on cmd I receive this error:

    An error occured while installing capybara-webkit (0.8.0), and Bundler cannot co
    ntinue.
    Make sure that `gem install capybara-webkit -v '0.8.0'` succeeds before bundling
    .

How can I install capybara-webkit on Windows 7?

I also tried to follow other instructions found here on Stackoverflow to run the Bundle without test, but it doesn't work.

I hope you can help.

I can not build a VM on Ubuntu, so don't suggest me to do that and I don't have a Mac.
