有什么办法可以解决这个问题吗？？运行 ruby script/delayed_job 运行良好。

标签： ruby-on-rails ruby delayed-job

【解决方案1】：

您可以在单独的提示符中手动启动它，而不是 rake jobs:work：ruby script/delayed_job

那里没有分叉到后台，因为您是直接调用脚本。

希望有所帮助。

【解决方案2】：

错误告诉您延迟作业使用的守护进程 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，或者切换到 Linux 或 Mac OS X 进行 Rails 开发。
