将 mac 系统切换成英文后，使用 git 命令出现如下错误:

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.UTF-8"

    are supported and installed on your system.

perl: warning: Falling back to the standard locale ("C").

解决方法

在 ~/.bash_profile 最后一行添加

export LC_ALL=C
