ruby-on-rails - Rails Rack 1.0 错误

Question

当我尝试启动脚本/服务器时出现此错误:

/opt/ruby1.8/lib/ruby/site_ruby/1.8/rubygems.rb:827:in `report_activate_error': RubyGem version error: rack(1.0.0 not ~> 1.0.1) (Gem::LoadError)
 from /opt/ruby1.8/lib/ruby/site_ruby/1.8/rubygems.rb:261:in `activate'
 from /opt/ruby1.8/lib/ruby/site_ruby/1.8/rubygems.rb:68:in `gem'
 from /opt/ruby1.8/lib/ruby/gems/1.8/gems/actionpack-2.3.5/lib/action_controller.rb:34
 from /opt/ruby1.8/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require'
 from /opt/ruby1.8/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'

 from /opt/ruby1.8/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/commands/server.rb:2

 from /opt/ruby1.8/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'
 from script/server:3

这很烦人，因为，我做到了:

Successfully installed rack-1.1.0
1 gem installed
Installing ri documentation for rack-1.1.0...
Installing RDoc documentation for rack-1.1.0...

但它总是说那个错误。我有 Rails 2.3.5，但我不认为错误与 Rails 相关，但更像是我的服务器相关，哈哈。

感谢帮助!

您安装了 Rack 1.1.0，所需版本为 1.0.x。

$ gem uninstall rack
$ gem install rack -v 1.0.1
