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/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，但我认为错误与 Rails 无关，但更像是与服务器相关的大声笑。

感谢帮助！

您安装了 Rack 1.1.0，需要的版本是 1.0.x。

$ gem uninstall rack
$ gem install rack -v 1.0.1

以上工作，安装时，你必须指出版本：“-v 1.0.1”

由于某种原因，否则它将无法正常工作。
