我需要从 rails 运行一些外部操作系统命令，我需要向用户显示它们的输出和退出代码。我检查了Delayed::Job API，但没有看到如何获取作业的标准输出。尝试过BJ (BackgroungJob) - 它有 stdout、stderr 和 exit_status 方法，但它在 rails 开始时失败：
~/my_src/ruby_apps/ro > script/rails c

script/rails:6: stack level too deep (SystemStackError)
似乎它与 3.2.3 不兼容
请帮助我从延迟的工作中获取标准错误、标准输出和退出代码，或者建议类似的 BJ。
