我没有对 ruby 文件进行任何更改，只是对布局进行了一些更改，并且在我的服务器上的 Papertrail 中看到以下错误。 我做了一些挖掘，似乎找不到答案。
此外，相同的代码库在 QA 系统中运行，没有错误。 两台服务器位于同一版本Cedar-14上，唯一的区别是Prod服务器具有工作线程Dyno，而QA没有。

您的生产服务器工作线程dyno尝试运行bundle exec rake jobs:work(检查您的Procfile(。看起来你没有那个任务。它通常应该在lib/tasks/jobs.rake.
如果你扩大你的QA员工规模，他们也会失败。
在查看了 Heroku 上的配置后，我们遵循相同模式的所有其他应用程序都不使用 jobs：work 或具有 jobs.rake 文件。 工作人员被错误地打开。 调查确实提供了一些线索，所以谢谢斯坦。
