为什么我会在 Mongrel 上的源代码水平较高时收到 Namerror？

Question

我从 github 下载了该项目并尝试在 mongrel 上按原样运行它，但出现此错误：

我正在运行 Ruby 1.8.7 和 Rails 2.3.5

在你的 config/environment.rb 中试试这个

之后：需要 File.join(File.dirname(FILE), 'boot')

if Gem::VERSION >= "1.3.6" 
    module Rails
        class GemDependency
            def requirement
                r = super
                (r == Gem::Requirement.default) ? nil : r
            end
        end
    end
end

及之前： Rails::Initializer.run 做 |config|
