ruby-on-rails - 在 Mac OS X Lion 上安装 Ruby 1.9.3 和 Rails 3.1.3 时出错

Question

当我想在 OS X 上安装 Ruby 1.9.3 时出现错误。我发现大部分问题都来自未安装 xCode。所以，我安装了它，但问题仍然存在，所以，这里是:

MacBook-Pro-de-Arnaud:~ Arnaud$ rvm install 1.9.3
Installing Ruby from source to: /Users/Arnaud/.rvm/rubies/ruby-1.9.3-p0, this may take a >while depending on your cpu(s)...

ERROR: There has been an error while running configure. Halting the installation.

所以，我决定让 1.8.7 直接转到 Rails，安装似乎进行得很顺利，但没有安装 :/

谁有解决办法吗？
