Is there any solution to solve out this problem?? it's working fine with ruby script/delayed_job run.

The error is telling you that the Daemons gem used by Delayed Job does not work on Windows, because there is no fork API in Windows (fork is a UNIX/Linux system call). You need to switch to a background processing library that is compatible with Windows, or switch to Linux or Mac OS X for your Rails development.

Instead of doing rake jobs:work you can manually start it in a separate prompt: ruby script/delayed_job

There is no forking to the background there, since you're invoking the script directly.

Hope that Helps.
