ChildProcess is throwing that error, yes, but it is doing so because require 'ffi' didn't work.

childprocess/lib/childprocess/windows.rb

Lines 3 to 7 in 4422792

begin
require 'ffi'
rescue LoadError
raise ChildProcess::MissingFFIError
end

If the require statement is failing, then the problem is probably not on the ChildProcess side of things. What happens if you try to load FFI in your code before loading ChildProcess?

require 'ffi'
require 'childprocess'

hello @nikolairoshchin. Were you able to figure this out? I'm having the same issue.

Hello, unfortunately i can say nothing about it. I don't remember and have deleted sources. Sorry

childprocess gem will no longer use/requireffi as of version 5.x, which was just released.
