Ruby守护进程挂起在rails上

我在使workling守护程序正常工作时遇到问题。我跑的时候:

ruby script/workling_client run

守护程序开始加载rails,但是无法挂起。当我终止进程时,堆栈跟踪始终是相同的:

/Library/Ruby/Gems/1.8/gems/activesupport-2.1.2/lib/active_support/core_ext/load_error.rb:32:in `new': Interrupt

如果我在没有守护进程库的情况下运行脚本,它将按预期工作。事实上,我在使用守护程序gem加载任何需要我的rails环境的东西时遇到了麻烦。有什么想法吗?

更新:workling_client将工作程序listen.rb作为守护程序加载。我没有在listen.rb中加载rails,而是更改了它,以便在workling_client中加载它,并且该过程顺利进行。因此,我无法在守护程序脚本中加载rails: - (

您可以发布启动守护程序脚本的代码吗?我知道可以在守护进程脚本中加载rails,因为我们是为delayed_jobs脚本执行的。

脚本的初始部分:

require File.expand_path(File.join(File.dirname(__FILE__), '..', 'config',
      'environment'))

调整rails项目中的environment.rb文件。然后,该过程继续进行守护:

Worker::Command.new(ARGV, :workers => worker_config).daemonize

我们的脚本在执行daemonize步骤之前加载rails。如果这不起作用,请包括脚本加载rails的方式。

尝试在没有显示器的情况下开始工作:

options = {
  :app_name   => "workling",
  :ARGV       => ARGV,
  :dir_mode   => :normal,
  :dir        => File.join(File.dirname(__FILE__), '..', 'log'),
  :log_output => true,
  :multiple   => false,
  :backtrace  => true,
  :monitor    => false
}
