Faye服务器未启动或启动

Question

我正在关注railscast并严格按照说明操作。我甚至使用net.tutsplus的faye.ru代码在根目录中设置faye.ru文件。

这里的faye.ru文件：

require 'faye' 
faye_server = Faye::RackAdapter.new(:mount => '/faye', :timeout => 45) 
run faye_server 

当我尝试用rackup faye.ru -s thin -E production启动服务器，

我得到以下错误：

/Users/TonyNg/faye-tutorial/faye.ru:3:in `block in <main>': undefined local variable or method ` ' for #<Rack::Builder:0x00000100918420 @ins=[]> (NameError)

    from /Users/TonyNg/.rvm/gems/ruby-1.9.3-p0@rails313/bin/rackup:19:in `<main>' 

这似乎只是工作对瑞恩来说，但我运气不好。

Answer 1

我找到了解决方案。我不是跑rackup -s thin -E production config.ru（config.ru的代替faye.ru），并得到了工作服务器，包括：

>> Thin web server (v1.3.1 codename Triple Espresso) 
>> Maximum connections set to 1024 
>> Listening on 0.0.0.0:9292, CTRL+C to stop 

显然，Rack的开发中间件，因为我在使用薄不薄带异步响应工作这个程序。
