我有一个Rails 5应用程序，它有几种引导模式中包含的表单。水豚阅读模态内容时遇到困难。从阅读其他几篇堆栈溢出文章，似乎我需要安装capybara-webkit gem。但是，我在安装时遇到问题。Rails - 安装capybara-webkit时遇到问题
在我最初的安装，我得到了一个错误，说：
Command 'qmake ' not available
extconf failed, exit code 1
Gem files will remain installed in
/Users/johnseabolt/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/capybara-webkit-1.14.0 for inspection.
Results logged to
An error occurred while installing capybara-webkit (1.14.0), and Bundler cannot continue.
Make sure that `gem install capybara-webkit -v '1.14.0'` succeeds before bundling.
环顾了一下，看来我需要安装QT。所以，我尝试使用从这篇文章的说明安装：https://github.com/thoughtbot/capybara-webkit/wiki/Installing-Qt-and-compiling-capybara-webkit
我在OS X上的El Capitan的，所以我跑：
brew install [email protected]
然后我打这个进入命令行，每个指令（我。相信这可能是在那里我搞砸了）：
我尝试安装宝石一遍，得到了确切的同样的问题：
