我现在使用这个:

$ cat /etc/environment
...
LC_ALL=en_US.UTF-8
LANG=en_US.UTF-8

然后注销SSH会话，重新登录。

旧的回答:

只有这一点对我有帮助:

$ locale
LANG=en_US.UTF-8
LANGUAGE=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"

LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=en_US.UTF-8

Use:

export LANGUAGE=en_US.UTF-8
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
export LC_CTYPE=en_US.UTF-8

它适用于Debian。我不知道为什么，但是locale-gen没有结果。

重要!这是暂时的解决办法。它必须在每个会话中运行。

在Arch Linux中使用英国键盘和地区，我有以下错误:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LANG = "en_US.utf8"

在/etc/profile中导出我的locale并没有修复它。 不过，我确实通过编辑/etc/locale修复了这个问题同时启用en_US. gen。perl期望找到的Utf8语言环境，并运行local-gen。

(我使用的pac-manager使用AUR的一大堆perl模块，所以在我的特殊情况下重新安装perl将是一个麻烦。)

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

另一个与git相关的答案:

问题的根源可能是Git服务器。如果所有这些都失败了，请尝试在服务器上执行dpkg-reconfigure区域设置(或适合您的发行版的任何设置)。
