我试图在我的Mac上安装rails,但每次我在命令行输入sudo gem install rails时,都会收到以下错误消息.我被困了一段时间,希望你能帮忙.

Building native extensions.  This could take a while...
    ERROR:  Error installing rails:
ERROR: Failed to build gem native extension.
    /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby extconf.rb
    mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/include/ruby.h


    Gem files will remain installed in /Library/Ruby/Gems/2.0.0/gems/atomic-1.1.14 for inspection       
    Results logged to /Library/Ruby/Gems/2.0.0/gems/atomic-1.1.14/ext/gem_make.out

解决方法

如果您尝试安装Rails 4.0,它需要RubyGems 2.0.3,因此您必须使用以下命令更新系统

gem update --system 2.0.3

然后继续安装.

希望它有所帮助
