perl：警告：在Windows XP / 7上设置区域设置失败

Question

在Windows XP / 7上，我在运行脚本时突然收到以下警告：

perl: warning: Setting locale failed.   
perl: warning: Please check that your locale settings:      
LC_ALL = "C",       
LANG = "C"      
are supported and installed on your system.     
perl: warning: Falling back to the standard locale ("C").       
perl: warning: Setting locale failed.   
perl: warning: Please check that your locale settings:  
LC_ALL = "C",   
LANG = "C"  
are supported and installed on your system.     
perl: warning: Falling back to the standard locale ("C").

我不知道该怎么做才能解决这个问题。

编辑：我正在使用Perl 5.012002
