有人可以解释为什么下面的代码不会产生传递的块吗?
require 'daemons'
t = Daemons.call do
# This block does not start
File.open('out.log','w') do # code don't get here to open a file
|fw|
10.times {
fw.puts "=>#{rand(100)}"
sleep 1
}
end
end
#t.start # has no effect
10.times {
puts "Running ? #{t.running?}" # prints "Running ? false" 10 times
sleep 1
}
t.stop
puts 'finished'
