Process.fork is not supported by this Ruby

[enumag]

Hello. I wanted to use the parallel gem but I'm getting this error. What's going on and how can I fix it please?

[grosser]

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

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

[enumag]

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

[grosser]

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

[enumag]

Does these ractors work on Windows?

[grosser]

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

[enumag]

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

[grosser]

ah yeah, fork does not work on windows
