centos7.2 perl: warning: Setting locale failed.解决办法

刚将自己系统切换到英文状态，在使用item链接远程ssh编译文件时，报以下错误，记录一下。

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
    LANGUAGE = (unset),
    LC_ALL = (unset),
    LC_CTYPE = "UTF-8",
    LANG = "en_US.utf8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

解决办法

vim /etc/profile
#在最后一行添加
export LC_ALL=C
:wq!
source /etc/profile

再次进行编译时没有错误提示了。
