Mina does not work on windows due to open4 gem

[simonharrer]

When calling mina deploy -s, mina errors out with the message

mina aborted!
fork() function is unimplemented on this machine

(See full trace by running task with --trace)

I called this mina command from within my git bash (msysgit installation) on a Windows 7 64 bit machine. The problem is located at open4 which tries to use the fork command not available on windows.

Is windows support planned?

Try putting this in your deploy.rb:

set :term_mode, :exec  if Process.respond_to?(:fork)

See if it works. I'd love to commit this fix, but I don't have a Windows machine to test, so it'd be nice if any Windows users out there can test out my fix.

If that doesn't work (maybe Process.fork exists in Windows, even if it doesn't work?), please try:

require 'rbconfig'

set :term_mode, :exec  if RbConfig::CONFIG['host_os'] =~ /mswin|mingw/

@rstacruz I got the same error running mina setup and the second solution you posted worked for me. Win7 64bit as well. Thanks 👍

Btw, can anyone confirm if Net::SSH works in Windows? Been contemplating on moving from open4 to net-ssh which may solve a few headaches along the way. cc @mikong

@jeremyharris Thanks, I'll implement it then.
