//警告信息
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
	LANGUAGE = "”zh_CN:zh:en_US:en”",
	LC_ALL = (unset),
	LC_MEASUREMENT = "zh_CN.UTF-8",
	LC_PAPER = "zh_CN.UTF-8",
	LC_MONETARY = "zh_CN.UTF-8",
	LC_NAME = "zh_CN.UTF-8",
	LC_ADDRESS = "zh_CN.UTF-8",
	LC_NUMERIC = "zh_CN.UTF-8",
	LC_TELEPHONE = "zh_CN.UTF-8",
	LC_IDENTIFICATION = "zh_CN.UTF-8",
	LC_TIME = "zh_CN.UTF-8",
	LANG = "zh_CN.GBK"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

解决方法：设置locale相关环境变量，在 .bashrc 文件末尾添加以下内容：

export LANGUAGE=en_US.UTF-8
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

然后运行：

source ~/.bashrc
