perl: warning: Setting locale failed. 错误处理

运行Perl时报出以下错误：

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

这里给出在 Mac Lion (10.7) 和 Cygwin (Windows 10) 下的解决办法。

找到 bashrc 或 bash_profile 文件将下面的代码添加到其中。

# Setting for the new UTF-8 terminal support in Lion
export LC_CTYPE=en_US.UTF-8
export LC_ALL=en_US.UTF-8

如果是使用的zsh, 则编辑 zshrc:

# Setting for the new UTF-8 terminal support in Lion
LC_CTYPE=en_US.UTF-8
LC_ALL=en_US.UTF-8

在ubuntu中如果使用了 debootstrap 工具创建文件系统，请执行下面的命令：

sudo locale-gen en_US.UTF-8

执行失败则
