我有一個Rails 5應用程序，它有幾種引導模式中包含的表單。水豚閱讀模態內容時遇到困難。從閱讀其他幾篇堆棧溢出文章，似乎我需要安裝capybara-webkit gem。但是，我在安裝時遇到問題。Rails - 安裝capybara-webkit時遇到問題
在我最初的安裝，我得到了一個錯誤，說：
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.
環顧了一下，看來我需要安裝QT。所以，我嘗試使用從這篇文章的說明安裝：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]
然後我打這個進入命令行，每個指令（我。相信這可能是在那裏我搞砸了）：
我嘗試安裝寶石一遍，得到了確切的同樣的問題：
