【问题描述】：
做了sudo port install curl-ca-bundlelink之后就开始有问题了，不知道是不是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:

在安装 curl-ca-bundle 之前，所有这些都使用了以下语句。
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：如果我删除 config.middleware.use "Rack::ResponseTimer" 它会起作用。
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
这是什么错误？我该如何解决？我必须重新安装 Phusion Passenger？
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？）
P.S.：如果您需要其他信息，请告诉我。
【问题讨论】：
-
为什么是你使用
config.middleware.use "Rack::ResponseTimer"？ -
这是来自railscasts.com的一个简单例子
-
那么 test-hyphen 是否与 1.9 兼容，在这里？
