我是一名铁路新手。我正在努力让一个简单的 helloworld rails 应用程序（无数据库）在共享主机上工作。

开发日志

Processing ApplicationController#index (for 122.61.170.222 at 2012-12-17 17:46:09) [GET]

ActionController::RoutingError (No route matches "/Say/hello" with {:method=>:get}):


Rendering rescues/layout (not_found)

导轨设置 http://scifiwear.com/rails_setup.png

我的子域设置：http ://scifiwear.com/subdomain.png

子域设置 http://scifiwear.com/subdomain.png

服务器版本：

Ruby 版本：1.8.7 Gem 版本：1.8.16 Rails 是 2.3.14

我配置 helloWorld 应用程序的步骤：

  1. 使用 Web 表单创建应用程序http://scifiwear.com/rails_setup.png

  2. cd myapp14

  3. ruby 脚本/生成控制器说再见

  4. http://myapp14.scifiwear.com/ 快乐！

5 http://myapp14.scifiwear.com/say/hello不开心！

杂种日志：

我的 routes.rb 的最后 4 行：（未触及）

# consider removing or commenting them out if you're using named routes and resources.

map.connect ':controller/:action/:id'

map.connect ':controller/:action/:id.:format'

end

任何建议表示感谢。

尝试为上一个问题给出的答案：在共享托管服务器上运行 Ruby on Rails 应用程序的问题；在这种情况下，它们可能会有所帮助。

我尝试在本地重现相同的错误，使用rails 2.3.14and ruby 1.8.7-p371; 没有收到错误信息。路由文件与您所拥有的类似。

日志跟踪如下：

Processing SayController#hello (for 127.0.0.1 at 2012-12-20 15:52:23) [GET]
Rendering say/hello
Completed in 35ms (View: 34, DB: 0) | 200 OK [http://localhost/say/hello]

鉴于此托管服务器上的 ruby​​ 和 rails 版本非常旧，您可能很难获得有关此安装所面临问题的帮助。而且您在学习这些概念时也会遇到困难。

我的建议是让您切换到使用最新版本的 ruby​​ 和 rails（并了解使用 rails 进行 Web 开发的最佳实践），遵循 Michael Hartl 的优秀且免费提供的在线书籍：Ruby on Rails 教程
