在debian下安装程序时，有时候会因为本地设置没有设置好，Per会给出下面的错误提示：
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LANG = "zh_CN.UTF-8"
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
要解决这个问题，其实很简单，只要执行下面几条命令，一切都会OK：
debian:~# apt-get install locales
debian:~# dpkg-reconfigure locales
debian:~# locale
下面是我执行这几条命令的显示：
debian:~# apt-get install locales

在执行第二条命令时，按照提示，选择你想要的local就OK了。
第三条命令是用来查看都安装了哪些local。
