所以我在 Fedora 17 上尝试安装 Capybara Webkit。我按照此处的说明为该项目的另一个（几乎相同）分支进行了捆绑安装，所以我知道它可以工作。

当我尝试时bundle install，它有这个错误。任何人都有想法，还是我应该用 co 记录一个错误？

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

安装 capybara-webkit (0.12.1) 时出错，Bundler 无法继续。gem install capybara-webkit -v '0.12.1'在捆绑之前 确保成功。

0.12.1 版是 gem 的一个过时版本 - 我在为我的旧项目安装类似版本时遇到了很多麻烦。

我建议升级到较新的版本 - 依赖项会更新，安装会少很多麻烦。

capybara-webkit 依赖于 Qt 的 WebKit 实现，这是一个跨平台的开发工具包。您需要下载 Qt 库来构建和安装 gem。QT下载安装说明：https ://github.com/thoughtbot/capybara-webkit/wiki/Installing-Qt-and-compiling-capybara-webkit
