Process.fork is not supported by this Ruby about parallel HOT 7 CLOSED

need to use threads if fork is not supported
you can use threads to spam processes

Parallel.in_threads(4) do
  `echo hey`
end

from parallel.

Unfortunately I don't think threads will work in my case. I need to do some work in separate process.

from parallel.

then chose a different ruby or make your threads fork as I showed
... can also try ractors, see #317 but that's pretty risky/new

from parallel.

Does these ractors work on Windows?

from parallel.

yeah on ruby 3.0+
... doubt it works on jruby, so not really an option for you afaik

from parallel.

Sorry but I'm a newbie. I don’t even know what jruby is. If I'm somehow using it then I'm not aware of it.

EDIT ah some sort of Java implementation of Ruby... no definitely didn't install that... I'm just using regular Ruby 3.1 for Windows

from parallel.

ah yeah, fork does not work on windows

from parallel.
