LANGUAGE=en_US:
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"

LC_ALL=zh_CN.UTF-8
ubuntu@VM-14-193-ubuntu:~$

出现错误，说明没有安装zh_CN.UTF-8语言。

查看当前系统已安装的语言

ubuntu@VM-14-193-ubuntu:~$ locale -a
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_COLLATE to default locale: No such file or directory
C
C.UTF-8
POSIX
en_US
en_US.iso88591
en_US.utf8
ubuntu@VM-14-193-ubuntu:~$ 

确实没有安装zh_CN.UTF-8语言。

安装缺少的语言

sudo locale-gen zh_CN.UTF-8

再次查看就ok了。
