rails -v

$ script/server

    from /Users/bmalets/.rvm/rubies/ruby-1.8.7-p371/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require' 
    from /Users/bmalets/.rvm/rubies/ruby-1.8.7-p371/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `require' 
    from /Users/bmalets/.rvm/gems/[email protected]/gems/activesupport-2.3.2/lib/active_support.rb:56 
    from /Users/bmalets/.rvm/rubies/ruby-1.8.7-p371/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require'

当我尝试安装宝石，我有：


$ rake gems:install 
(in /Users/bmalets/Documents/ror_projects/myapp) 
rake aborted! 
undefined method `name' for "actionmailer":String

您的Rails版本无望地过时了。我不知道你遵循的是什么指南，但是我会为Rails 3.2和Ruby 1.9.3找到一个。 – Veraticus 2013-03-17 03:21:18

谢谢，我知道uptodate导轨版本:)现在我正在将旧导轨项目升级到新的导轨，并尝试启动它来了解功能 – bmalets 2013-03-17 03:24:38

请给我指导rails_3，你找到了。非常感谢 – bmalets 2013-03-17 03:26:36

我重新安装了RubyGems，它帮助。
