Nokogiri的Rails包安裝無法正常工作

Question

我開始了一個新的Rails項目，將其放入其中，然后嘗試捆綁安裝

我收到以下錯誤

安裝nokogiri（1.6.7）時發生錯誤，並且Bundler無法繼續。 捆綁之前，請確保gem install nokogiri -v '1.6.7'成功。

我很確定這是A級問題，我嘗試使用Google搜索，但沒有發現任何問題，希望我沒有忽略它

謝謝你的幫助

編輯：如果我嘗試手動安裝nokogiri它給出以下錯誤

您需要安裝OS X開發工具（最后輸出會顯示）。

以下是一些有關安裝xcode的好的說明： 在Mac上安裝Ruby on Rails以進行Ruby on Rails開發（大約一半）

如果可行，這似乎是將您送往目的地的最簡單方法。

如果這樣不起作用，您可能會在這里找到幫助：
