Mac OSX setsid command not found

[mehrna]

I'm using Mac OSX (high sierra) as a develop machine. After running ./yii queue/listen on DbQueue (MySQL) it shows :

Listening to queue...
queueSize: 4011 , opened: 0 , limit: 1
Running new process...
Running setsid /usr/local/Cellar/php/7.2.10/bin/php /Users/mehran/Projects/www/html/SamaNext/yii queue/run (mode: single)
Running in sync mode
sh: setsid: command not found
Done, cleaning:1578
Cleanning up 1578
Error
sh: setsid: command not found

It seems that setsid is missing on OSX.
what is your idea @petrabarus ? what should I do?

For those how need to know, just use this library:
https://github.com/jerrykuch/ersatz-setsid
This is an ersatz setsid command for those Unixes (e.g. Mac OS X)
that don't have one. It's intended to work like (or enough like)
the one from the util-linux-ng package that I can run the RabbitMQ
test suite as of Summer 2011 on a Mac OS X dev machine.
