未能在Mac OS X上安裝nokogiri和webrat

Question

我試圖在我的Mac上安裝webrat，但是我有錯誤，圖標v.h丟失。這裏是日誌：

Building native extensions. This could take a while... 
ERROR: Error installing webrat: 
ERROR: Failed to build gem native extension.

Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/nokogiri-1.4.1 for inspection.

奇怪的是，iconv.h已經在/ opt/local/include /目錄中。

任何人都可以推薦一個解決方案嗎？

Answer 1

好吧，我解決它在我自己的。 經過幾天的研究和嘗試，我發現，我的g ++和gcc的安裝被破壞了。我已經通過macports安裝了g ++的更新，並且在我當前用戶的.profile文件中，來自macports的PATH var中有一個值。我刪除它，現在它可以工作。

的PATH VAR應該是這樣的：

export PATH=/opt/local/bin:/opt/local/sbin:$PATH 

Answer 2

上引入nokogiri網站更多的幫助，使用MacPorts的或自制爲Mac OS X上安裝：

對於iconv相關問題，請參考github上的這個問題：
