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:Settinglocalefailed.
perl:warning:Pleasecheckthatyourlocalesettings:
LANGUAGE=(unset),
LC_ALL=(unset),
LANG="zh_CN.UTF-8"
aresupportedandinstalledonyoursystem.
perl:warning:Fallingbacktothestandardlocale("C").
locale:CannotsetLC_CTYPEtodefaultlocale:Nosuchfileordirectory
locale:CannotsetLC_MESSAGEStodefaultlocale:Nosuchfileordirectory
locale:CannotsetLC_ALLtodefaultlocale:Nosuchfileordirectory
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-getinstalllocales
debian:~#dpkg-reconfigurelocales
debian:~#locale
下面是我执行这几条命令的显示（粗体部分是命令行）：
debian:~#apt-getinstalllocales

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。
如果还不行，需要把LC_ALL=设置成zh_CN.UTF-8
