perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = "zh_CN:zh",
LC_ALL = (unset),
LC_TIME = "zh_CN",
LC_MONETARY = "zh_CN",
LC_ADDRESS = "zh_CN",
LC_TELEPHONE = "zh_CN",
LC_NAME = "zh_CN",
LC_MEASUREMENT = "zh_CN",
LC_IDENTIFICATION = "zh_CN",

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
解决方法：
1、配置想要的locale
cp /user/share/i18n/SUPPORTED /var/lib/locales/supported.d/local
打开/var/lib/locales/supported.d/local文件，将其中除了en_*和zh_*之外的值都删掉，然后
locale-gen --purge
2、使用locale命令，将输出的值：
LANG=zh_CN.UTF-8
LANGUAGE=zh_CN:zh
LC_CTYPE="zh_CN.UTF-8"
LC_NUMERIC=zh_CN
LC_TIME=zh_CN
LC_COLLATE="zh_CN.UTF-8"
LC_MONETARY=zh_CN
LC_MESSAGES="zh_CN.UTF-8"
LC_PAPER=zh_CN
LC_NAME=zh_CN
LC_ADDRESS=zh_CN
LC_TELEPHONE=zh_CN
LC_MEASUREMENT=zh_CN
LC_IDENTIFICATION=zh_CN
LC_ALL=
拷贝到/etc/environment文件中即可。
