机架错误安装问题。服务器未启动
我刚刚安装了 Rack-Bug 并在 config 文件夹中创建了它所需的中间件文件。但我无法启动我的服务器。 我使用 Rails 2.3.4 和 Ruby 1.8.7。
/usr/lib/ruby/gems/1.8/gems/activesupport-2.3.4/lib/active_support/dependencies.rb:443:in `load_missing_constant': uninitialized constant IPAddr (NameError)

我不知道我做错了什么。任何帮助都会很棒。

我也有同样的问题。
解决方案是将以下行放在environment.rb的顶部（ruby核心类的要求：http://ruby-doc.org/core/classes/IPAddr.html):
需要 'ipaddr'
I had the same problem.
The solution is to put the following line at the top of your environment.rb (requirement of a ruby core class: http://ruby-doc.org/core/classes/IPAddr.html):
require 'ipaddr'
