有没有解决这个问题的解决方案？ 它与ruby脚本/ delayed_job运行正常。

Answer 1

该错误告诉您，Delayed Job使用的Daemons gem在Windows上不起作用，因为Windows中没有fork API（ fork是UNIX / Linux系统调用）。 您需要切换到与Windows兼容的后台处理库，或切换到Linux或Mac OS X以进行Rails开发。

Answer 2

而不是做rake jobs:work你可以在一个单独的提示中手动启动它： ruby script/delayed_job

因为你直接调用脚本，所以没有分支到那里的背景。

希望有助于。
