我正在尝试在XP上构建capybara-webkit。我关注this instruction。我说：
8) Clone latest version of capybara-webkit from Github:
$ git clone git://github.com/thoughtbot/capybara-webkit.git
9) Bundle/Install capybara-webkit version:
$ cd ruby193\capybara-webkit
$ bundle install
我是第一次这样做的。它安装了一些宝石。然后我按照指示步骤但无法构建capybara-webkit。因此，为了再次开始，我删除了所有手动安装的gem。现在我遵循所有相同的步骤，但bundle install不再起作用。我说所有的宝石都存在：
C:\RailsInstaller\Ruby1.9.3\lib\ruby\gems\1.9.1\gems>cd capybara-webkit
C:\RailsInstaller\Ruby1.9.3\lib\ruby\gems\1.9.1\gems\capybara-webkit>bundle install

Your bundle is complete!
Use `bundle show [gemname]` to see where a bundled gem is installed.
但现在我用bundle show检查这些宝石，但它说它们都被删除了：
C:\RailsInstaller\Ruby1.9.3\lib\ruby\gems\1.9.1\gems\capybara-webkit>bundle show sinatra
The gem sinatra has been deleted. It was installed at:
C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/sinatra-1.3.5
C:\RailsInstaller\Ruby1.9.3\lib\ruby\gems\1.9.1\gems\capybara-webkit>bundle show selenium-webdriver
The gem selenium-webdriver has been deleted. It was installed at:
C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/selenium-webdriver-2.27.2
C:\RailsInstaller\Ruby1.9.3\lib\ruby\gems\1.9.1\gems\capybara-webkit>bundle show mini_magick
The gem mini_magick has been deleted. It was installed at:
C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/mini_magick-3.2.1
bundle install表示它们存在但bundle show表示它们被删除了怎么办？所以bundle install不再起作用了。我怎样才能再次使用bundle install再次安装这些宝石？
