将LC_TYPE环境变量设置为默认的区域语言“C”将有助于消除此警告。

执行export LC_CTYPE="C"，然后尝试执行perl命令。

附注:您需要在/etc/environment文件或/etc/default/locale文件中设置此变量以获得永久解决方案。

我有多个用户使用不同的外壳，所以在我的情况下，这解决了:

检查哪个外壳 echo $ 0 如果bash #设置locale\nLC_CTYPE=en_US. utf -8\nLC_ALL=en_US. utf -8UTF-8" >> .bashrc 如果zsh #设置locale\nLC_CTYPE=en_US. utf -8\nLC_ALL=en_US. utf -8UTF-8" >> .zshrc

每当我在最新的Kali Linux版本上运行Perl脚本(比如enum4linux)时，都会遇到这个问题。

请看给出的警告信息。

perl: warning: Falling back to a fallback locale ("en_US.UTF-8").

另外，注意LC_ALL = (unset)

解决办法很简单。你所要做的就是设置它。

export LC_ALL=en_US.UTF-8

例如,

kali@kali:~$ export LC_ALL=en_US.UTF-8
kali@kali:~$

问题解决了

kali@kali:~$ enum4linux

对于永久解决方案，您可能希望将其添加到.bashrc文件中。

对于任何从iTerm2连接到DigitalOcean或其他云托管提供商的人。在macOS v10.13 (High Sierra)上运行app，在一些命令上得到这个错误:

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 a fallback locale ("en_US.UTF-8").

这为我解决了问题:

如果不关心语言环境问题，可以设置PERL_BADLANG=0。当然，这可能导致不正确的本地化。

如果您使用Mac OS X v10.10 (Yosemite)或以上版本来连接服务器Linux，您可以尝试这些步骤。

保持/etc/ssh/sshd-config文件原始 输入~/.bash_profile 出口LANG = " en_US " 出口LC_ALL = $朗。utf - 8 运行 dpkg-reconfigure地区 并选择“en_US”。utf - 8”
