麻烦在山狮上安装json宝石

Question

我尝试运行bundle install,它在json gem上停止了.所以我尝试运行运行sudo gem install json 1.7.3这是它崩溃的版本它给出了以下内容:

unknown109addaae0a6:introhive Jody$ sudo gem install json
Building native extensions.  This could take a while...
ERROR:  Error installing json:
    ERROR: Failed to build gem native extension.

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb
mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/ruby.h


Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/json-1.7.3 for inspection.
Results logged to /Library/Ruby/Gems/1.8/gems/json-1.7.3/ext/json/ext/parser/gem_make.out

然后,如果我查看gem_make.out文件,它看起来像这样:

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb
mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/ruby.h

我已经尝试确保安装了命令行工具,但是我对如何通过这个工具感到有点失落.

任何帮助,将不胜感激.谢谢

除了我正在使用RVM之外,我在安装JSON 1.7.4时遇到了类似的问题.无论如何,我为解决我的问题所做的是从developer.apple.com安装Xcode 4.4 ,一旦安装完毕,我必须安装Xcode的命令行工具.您可以通过启动Xcode然后单击Xco​​de> Preferences> Downloads并单击命令行工具旁边的install来安装命令行工具.

我最终不得不使用 ruby​​ 1.9.2 才能使其正常工作。
