断管 (Errno::EPIPE)

问题描述

我有一个 Broken pipe (Errno::EPIPE) 错误弹出，我不明白它是什么或如何修复它.完整的错误是:

i have a Broken pipe (Errno::EPIPE) error popping up and i don't understand what it is or how to fix it. the full error is:

example.rb:19:in `write': Broken pipe (Errno::EPIPE)
    from example.rb:19:in `print'
    from example.rb:19

我的代码的第 19 行是:

line 19 of my code is:

vari.print("x=" + my_val + "&y=1&z=Add+Num\r\n")

推荐答案

这意味着打印输出到的任何连接都不再连接.据推测，该程序是作为其他程序的输入开始的:

It means that whatever connection print is outputting to is no longer connected. Presumably the program began as input to some other program:

 % ruby_program | another_program

发生的事情是 another_program 在有问题的 print 之前的某个时间退出了.

What's happened is that another_program has exited sometime before the print in question.
