让 Rails 应用程序在 IronRuby Rack 下运行

Question

还有人玩ironruby吗？

我已成功在 IIS 5.1 下的本地计算机上运行 IronRuby.Rails.Example 项目。我现在正尝试以同样的方式运行我自己的演示 Rails 站点。

我的 web.config 与示例项目略有不同。我尝试只使用 IronRuby 1.0 中分发的内容以及我使用 gems 安装的内容。

我收到以下错误，这并没有让我继续下去：

D:/demo/config/boot.rb:66:在“退出”中： 退出（系统退出）

在尝试了许多不同的事情之后，我认为它在寻找宝石时遇到了问题。我已附上我的网络配置和ironrack.log。有人指出我做错了什么吗？

谢谢！

Answer 1

exit 是 ruby​​ 中以编程方式退出的方法。

rack 背后的想法是它是 ruby​​ web 框架和实际应用服务器之间的中间件。通过解耦，它让无数的 ruby​​ 框架（rails、sinatra、ramaze 等）针对单个接口，并且无数的应用程序服务器（mongrel、apache with guest、unicorn 等）也可以执行相同的操作。看起来 IR 人员正在尝试让机架与 IIS 一起工作。我快速搜索了机架上的 Rails 配置，发现 此页面

输出看起来类似于您在 Rails 服务器方法中看到的内容。我会尝试找出这是从哪里来的

require "config/environment"

ENV['RAILS_ENV'] = 'development'

use Rails::Rack::LogTailer
use Rails::Rack::Static
run ActionController::Dispatcher.new
) }.to_app exit

，并尝试使其更接近该指南中的内容。如果你找不到它，我会尝试在 IR 邮件列表上发帖。他们往往相当友好，而且由于目前这是一个边缘问题，因此他们可能是唯一拥有足够专业知识可以提供帮助的人。

祝你好运 ：-）
