无法在OS X El Capitan上安装capybara-webkit
升级到El Capitan后，我遇到安装capybara-webkit的问题。 已安装QT版本qt-4.8.7_1 。 bundle install给出权限错误， sudo gem install给出了另一个错误：
捆绑安装：

Make sure that `gem install capybara-webkit -v '1.7.1'` succeeds before bundling.
gem安装：

完整日志： 在此处输入链接描述
$ brew install qt $ brew link --overwrite qt $ bundle install
为我工作（rbenv / Yosemite 10.10.5（14F27））
简而言之：
$ brew upgrade $ which qmake $ rm `which qmake` $ brew install qt5 $ brew link --force qt5 $ bundle install
基于：
- capybara-webkitが捆绑安装できなかった话
- OS X El Capitan 10.11和Yosemite 10.10
