perl: warning: Please check that your locale settings:
    LANGUAGE = "en_HK:en",
    LC_ALL = (unset),
    LC_PAPER = "zh_CN.UTF-8",
    LC_ADDRESS = "zh_CN.UTF-8",
    LC_MONETARY = "zh_CN.UTF-8",
    LC_NUMERIC = "zh_CN.UTF-8",
    LC_TELEPHONE = "zh_CN.UTF-8",

    LC_TIME = "zh_CN.UTF-8",
    LC_NAME = "zh_CN.UTF-8",
    LANG = "en_HK.UTF-8"

修改~/.bashrc

在最底部添加　LC_ALL=C　所以可以这样运行

qifa@ts-server:~$ echo "export LC_ALL=C">>~/.bashrc
qifa@ts-server:~$ source ~/.bashrc
