覆盖 $ stdout 以重定向控制台输出：

You can use override $stdout to redirect the console output:

$stdout = File.new('console.out', 'w')

您可能还需要调用一次：

You may also need to call this once:

$stdout.sync = true

这将把所有输出重定向到文件。如果您要临时重定向输出，请确保您存储 $ stdout 的原始值，以便可以将其更改。

This will redirect all output to the file. If you want to temporarily redirect the output make sure that you store the original value of $stdout so you can change it back.
