Ruby on rails 重新确认返回的作业，但出现错误：“quot；没有这样的文件或目录-getcwd"；

我有一个非常简单的工作：

class MyJob
  @queue = :high

  def self.perform(user_id)
    user = User.find(user_id)
    MyMailer.send_email(user).deliver
  end

end

如果我手动运行它

MyJob.perform（some\u id）

。但是，当Rescue执行时，它返回以下错误：

Exception
    Errno::ENOENT Error
    No such file or directory - getcwd

你知道为什么会发生吗

谢谢

我开始在我的生产环境中遇到同样的问题。经过一些调查，我发现这是由于我的resque工作人员未能在每次capistrano部署时正确重新启动造成的

是的，天空。你说得对，它需要重新启动

有些人在尝试从已删除的目录运行后收到此错误

在切换数据库并保持服务器运行后，我收到了此错误。旧的服务器信息仍然显示，但我得到了这个错误。重新启动了rails服务器，新数据库一切正常

基本上，这意味着服务器上的状态发生了重大变化，您的环境需要重置/重新启动。

如何手动重新启动它们？rake resque:scheduler RAILS_ENV=production？？？Sky mayhew您是如何解决这个问题的？
