ruby - 无法在 Mac OS X 10.7.3 Lion 上的 ruby​​ 1.8.7 中加载 ruby​​-debug

Question

无法在 Mac OS X 10.7.3 Lion 上加载 ruby​​-debug。

不知道为什么路径不正确。

Ruby 版本是 1.8.7，这是 Lion 的标准版本。

已安装 Xcode

$ 

在Lion系统上查找ruby.h路径，路径不一样。

./Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/Ruby.framework/Versions/1.8/Headers/ruby.h
./Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/universal-darwin10.0/ruby.h

此时最好的方法是什么？

谢谢，

解决方案:需要安装 Xcode 4.3，然后必须从 Xcode Preferences-General 安装 Xcode Command Line Tools。

如果没有命令行工具，则会生成上述错误。

安装后，Ruby-Debug 会加载。
