i pry'd into:

def output_and_errors_from_command(cmd) #:nodoc: unless defined? Open3 begin require 'open3' require 'win32/open3' rescue LoadError end end begin require 'pry' binding.pry out, err, status = Open3.capture3(*cmd, :binmode => true) [out, err, status.exitstatus] rescue NotImplementedError, NoMethodError IO.popen( *cmd ) do |stdout| stdout.binmode [stdout.read, nil, nil] end end end

and found the command being constructed ran without errors when i ran it in my console directly
