sudo nano /etc/locale.gen

取消注释你想要使用的地区(例如en_US。utf - 8 utf - 8):

然后运行:

sudo /usr/sbin/locale-gen

来源:配置区域设置

perl -e exit
sudo localedef -i en_US -f UTF-8 en_DE.UTF-8
#                                   DE = German
# Use your country code en lieu of  DE

# The second "perl" should then not complain any more
perl -e exit

localectl list-locales # Just make sure it is OK

尝试重新安装:

localess apt-get install --reinstall locales

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:

在我的例子中，这是输出:

LANGUAGE = (unset),
LC_ALL = (unset),
LC_PAPER = "ro_RO.UTF-8",
LC_ADDRESS = "ro_RO.UTF-8",
....

解决方案是:

sudo locale-gen ro_RO.UTF-8

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。

kali@kali:~$ lsb_release -a
No LSB modules are available.
Distributor ID:    Kali

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。
