ruby-on-rails - Resque 作业返回错误 : "No such file or directory - getcwd"

Question

我有一份非常简单的工作:

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_id)它会完美运行。但是，当 Rescue 执行它时，它会返回此错误:

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

知道为什么会发生这种情况吗？

谢谢!

是的天空。您说得对，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。

我在切换数据库并让服务器保持运行后收到此错误。旧服务器信息仍在显示，但我收到此错误。重新启动我的 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/重启。
