-bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)

使用 locale 命令，查看错误原因，如下。

root@may:/var/www/WebChat# locale
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

使用 local-gen 安装 en_US 的 locale，解决问题，如下。

root@may:/var/www/WebChat# locale -a
