在 rake 任务中打印到屏幕 [英] Printing to screen in a rake task

问题描述

我有一个长期运行的 rake 任务.我不时地在屏幕上打印更新，让我知道任务进行了多远.

I have a long running rake task. Every now and then I print an update to the screen to let me know how far along the task has come.

puts "Almost there..."

我的问题是所有 puts 语句似乎都在某处缓冲，并且在任务完成之前不会打印到屏幕上.届时，它们将一次全部打印出来.

My problem is all the puts statements seem to buffer somewhere and won't print to the screen until after the task is complete. At which point, they will be printed all at once.

有什么方法可以强制它们在任务运行时打印吗?

Is there some way to force them to print as the task is running?

推荐答案

STDOUT.sync = true
