在Mac OS X Snow Leopard上使用RVM安裝Ruby 1.9.2的問題

Question

我剛剛開始學習Ruby，並試圖在Macbook Air上使用RVM安裝最新版本並且它一直在失敗。 我必須做錯事，因為在網上進行了大量搜索之后，我沒有看到有人在Ruby安裝過程中抱怨這個確切的錯誤。

采取的步驟：

Dima$ rvm install ruby-1.9.2-p290
Installing Ruby from source to: /Users/Dima/.rvm/rubies/ruby-1.9.2-p290, this may take a while depending on your cpu(s)...

ERROR: Error running 'make ', please read /Users/Dima/.rvm/log/ruby-1.9.2-p290/make.log
ERROR: There has been an error while running make. Halting the installation.

在此之后，如同建議的錯誤消息，我去查看make.log文件：

我不確定如何解讀這個，我最初的本能就是說我沒有安裝FFI，但我從來沒有在Ruby的任何安裝步驟中看到這個要求。 這是我的電腦特有的東西嗎？

任何有經驗的人的幫助將不勝感激。 對於帖子中任何缺失的部分提前道歉，因為我不完全確定如何解決這個問題。 請告訴我哪些其他信息有助於解決問題，我會將其添加到帖子中。

謝謝

當我開始在我的macbook pro上進行一些rails編程時，在使用rvm安裝ruby時遇到了一些錯誤。 不記得我得到的錯誤，但我必須安裝xcode然后我可以用rvm安裝ruby。

經過幾個小時的挫折后，我最終在我的Macbook Air上加載了Mac OS X Lion和Xcode 4，然后再次嘗試運行rvm install ruby-1.9.2-p290並且它沒有問題。
