Rails rack 1.0错误

Question

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 `require'
 from script/server:3

这很烦人,因为我做了:

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...

但它总是说错误.我有Rails 2.3.5,但我不认为错误是Rails相关,但更像是我的服务器相关的大声笑.

感谢帮助!

你安装了Rack 1.1.0,所需的版本是1.0.x.

$ gem uninstall rack
$ gem install rack -v 1.0.1
