更改语言环境

现在需将en_US.UTF-8改为zh_US.UTF-8，en改为cn。编辑配置文件如下：

$ sudo vi /etc/default/locale
LANG="zh_CN.UTF-8"
LANGUAGE="zh_CN:zh"
LC_ALL="zh_CN.UTF-8"

保存后执行locale查看，如果有报如下错误 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 说明没有安装

查看系统安装的locale

$ locale -a

安装locale

# locale-gen zh_CN.UTF-8
