Gem文件仍将安装在/Users/alonbond/.rvm/rubies/ruby-1.9.2-p290/lib/ruby/gems/1.9.1/gems/json-1.6.3中以供检查。结果记录到/Users/alonbond/.rvm/rubies/ruby-1.9.2-p290/lib/ruby/gems/1.9.1/gems/json-1.6.3/ext/json/ext/parser/gem_make.out

然后我尝试使用rails命令：

Alon-Weissfelds-MacBook-Pro:~ alonbond$ rails -v

  Rails is not currently installed on this system. To get the latest version, simply type:

    $ sudo gem install rails

    You can then rerun your "rails" command.

尝试从Mac应用商店或GCC编译器安装Xcode

通常Xcode可以解决所有这些问题。GCC并非100%符合所有GEM
