無法安裝水豚，WebKit的與OS X塞拉利昂

Question

我一直在試圖安裝與打捆的水豚，Webkit的寶石，並按照下列指示後：https://github.com/thoughtbot/capybara-webkit/wiki/Installing-Qt-and-compiling-capybara-webkit#macos-sierra-1012

我一直運行到Makefile中的錯誤不被發現。我已經更新了Homebrew，寶石系統，並用cli工具更新了Xcode 8，但無濟於事。非常感謝任何幫助！

Answer 1

以下的伎倆，我（用自制）：

brew install qt5 --with-qtwebkit 
brew link --force qt5 
gem install capybara-webkit 

注：這將需要一段時間才能安裝第一步，你需要安裝的Xcode。
