如何运行带有警告的所有Ruby脚本？ [英] How can I run all Ruby scripts with warnings?

问题描述

理想情况下，即使我在...时，我也可以运行Ruby脚本，默认情况下会打开警告通过Rake间接运行脚本，而不是直接在我直接运行时。

根据这个答案。

解决方案

RUBYOPT 环境变量定义默认选项，如警告等。

Unix / OS X / etc：

  export RUBYOPT = -w 
  

您可以将其放在Unix的启动脚本中，以便它设置为新的shell。

Windows：

 设置RUBYOPT = -w 
  

使用系统属性对话框将其设置为新shell /命令窗口。

How can I always run Ruby scripts with warnings turned on by default, by modifying my Unix or Windows environment variables?

Ideally this should work even when I'm running a script indirectly such as through Rake, not just when I'm running it directly.

Based on a comment in this answer.

解决方案

The RUBYOPT environment variable defines default options like warnings, etc.

Unix/OS X/etc:

export RUBYOPT=-w

You can put this in your startup script in Unix so it's set for new shells.

Windows:

set RUBYOPT=-w

Use the system properties dialog to set it for new shells/command windows.
