Phusion乘客问题：“无法启动Ruby（机架）应用程序”

Question

在完成sudo port install curl-ca-bundle 链接后，我开始遇到问题，但是我不知道这是否是由curl-ca-bundle引起的。

我有这个问题：

Ruby (Rack) application could not be started

These are the possible causes:

    *
      There may be a syntax error in the application's code. Please check for such errors and fix them.
    *
      A required library may not installed. Please install all libraries that this application requires.
    *
      The application may not be properly configured. Please check whether all configuration files are written correctly, fix any incorrect configurations, and restart this application.
    *
      A service that the application relies on (such as the database server or the Ferret search engine server) may not have been started. Please start that service.

Further information about the error may have been written to the application's log file. Please check it in order to analyse the problem.

Error message:
    uninitialized constant Rack::ResponseTimer
Exception class:
    NameError
Application root:
    /Users/<my_user_name>/Sites/pjtname.com/pjtname.com

因此，在终端中，我尝试运行

gem update

并且所有宝石都进行了更新，除了以下内容：

Updating text-hyphen
ERROR:  Error installing text-hyphen:
    text-hyphen requires Ruby version < 1.9.

在安装curl-ca-bundle所有这些都可以使用以下语句。

---

在config.ru文件中：

# This file is used by Rack-based servers to start the application.

    require ::File.expand_path('../config/environment',  __FILE__)
    run PjtnameCom::Application

---

在ROOT_RAILS/conf/application.rb ：

module PjtnameCom
  class Application < Rails::Application
    # Configure middlewares
    config.middleware.use "Rack::ResponseTimer"
    ...
  end
end

注意 ：如果删除config.middleware.use "Rack::ResponseTimer" 。

---

在ROOT_RAILS/libs/rack/response_timer.rb ：

module Rack
  class ResponseTimer
    def initialize(app)
      @app = app
    end

    def call(env)
      status, headers, response = @app.call(env)
      [status, headers, response]
    end
  end
end

那是什么错误？ 我该如何解决？ 我必须重新安装Phusion Passenger吗？

我用：

• Mac OS运行“雪豹” 10.6.6

• Ruby版本管理器（RVM）

• 阿帕奇

• Ruby on Rails v3.0.3（ 也许我必须升级到v 3.0.4？ ）

PS ：如果您需要其他信息，请告诉我。

在RAILS_ROOT/config/application.rb我忘记了（!!!!!）

# Custom directories with classes and modules you want to be autoloadable.
# config.autoload_paths += %W(#{config.root}/extras)
config.autoload_paths += %W(#{config.root}/lib)
