我知道其他人已经问过这个,但建议的修补程序似乎对我不起作用。我正在尝试使用Ruby 1.8.7在Mac OS X Lion上安装Rails v.3.2.3。在终端:
$ sudo gem install rails -v 3.2.3
然后我收到错误消息:
Building native extensions. This could take a while...
ERROR: Error installing rails:
ERROR: Failed to build gem native extension.

Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/json-1.7.0 for inspection.

我见过有人建议安装Xcode v.4.3.2,但我不确定是否需要对Xcode做一些特别的事情才能使Rails安装正常工作。任何帮助表示赞赏。

最简单的安装方式是使用RVM 这是一个非常好的指南:
