Question

我在Windows PC上的rails安装程序上创建了一个桌面浏览器应用程序。现在我正在尝试运行rails s -p3001 -e production -d。它不能在电脑上运行。

如何在Windows PC上分离应用程序服务器进程？

这是错误

Answer 1

错误消息非常清楚：fork() function is unimp lemented on this machine (NotImplementedError)。

rails服务器守护程序的方法是调用计算机上的fork system call。以下是rails repo：exit if fork

中的相关代码

Windows PC上的失败是因为Windows Operating System没有实现fork系统调用。

一个选项可能是按照this answer to What is the closest thing windows has to fork()?

中的建议在Windows PC上安装Cygwin

Answer 2

我已经参考了链接:: run rails in background process -windows

解决了这个问题

感谢Murthy的答案

在后台进程中运行rails -windows
