Run rails in background - windows

I created one desktop browser app on rails installer on windows machine. Now I am trying to run rails s -p3001 -e production -d

. It doesn't work on PC.

How to detach application server process on Windows PC?

Here is the error

Error message makes it very clear fork() function is unimp lemented on this machine (NotImplementedError)

.

Implemented the rail server process by calling fork system call

on the machine. Here is the relevant code from the rails repo:exit if fork



It doesn't work on Windows PC because it Windows Operating System

doesn't make a system call fork

.

One option might be to install Cygwin

on a Windows PC, as suggested in this answer to "What's the closest thing to windows for fork ()?"
