Question

我正在尝试在我的Mac上的rails上安装ruby，安装后我收到此错误。有谁能告诉我如何解决这个问题？

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:777:in `report_activate_error': RubyGem version error: rack(1.5.2 not ~> 1.4.5) (Gem::LoadError)

听起来好像这可能是你的问题：LoadError when installing rails on Mac(OS X 10.8.3)

您正在使用Ruby 1.8（正如您在堆栈跟踪中看到的那样），但可能尝试安装Rails 3.2.13，它根本不起作用 - 它不再受支持。

正如答案所说，你应该回去学习/使用RVM来安装更新版本的Ruby。
