Question

我最近使用RVM在Ubuntu 10上安装了RoR，一切似乎都运行良好但是当我尝试创建一个简单的应用程序以查看一切是否正常工作时，我得到了一个错误的错误：

josethernandezc@josethernandezc:~$ rails sample_app  

/home/josethernandezc/.rvm/gems/ruby-1.8.7-p334/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:55: uninitialized constant ActiveSupport::Dependencies::Mutex (NameError)

Answer 1

问题是ubuntu 10.10不支持activesupport gems.try再次安装activesupport gem，如果问题仍然存在，请参阅此博客http://railsappmadeasy.blogspot.com/这里我提到了在ubuntu 10.10上安装ROR的完整步骤。希望这会帮助你。

gem install rails --version [latest version 5.1.1]
