我有这段代码：
puts "Start"
loop do
Thread.start do
puts "Hello from thread"
exit
end
text = gets
puts "#{text}"
end
puts "Done"
我期望看到“开始”后跟“线程中的Hello”,然后我可以输入回复给我的输入.相反,我得到“开始”和“来自线程的Hello”,然后程序退出.
从退出文档：
Terminates thr and schedules another thread to be run. If this thread
@H_403_13@
is already marked to be killed,exit returns the Thread. If this is
the main thread,or the last thread,exits the process.但我以为我催生了一个新线程？为什么退出我的主要流程？
解决方法
您正在查看
Thread#exit文档. kill是
Kernel#exit,它终止了Ruby脚本.
puts "Start"
loop do
Thread.start do
puts "Hello from thread"
Thread.exit
end
text = gets
puts "#{text}"
end
puts "Done"
