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

对我来说，在Ubuntu 16.04 (Xenial Xerus)上，以下工作:

root@host:~#locale-gen en_GB.UTF-8
root@host:~#localectl set-locale LANG=en_GB.UTF-8,LC_ALL=en_GB.UTF-8

然后重新启动…

用zsh ohmyzsh，我把这个添加到。zshrc:

 # You may need to manually set your language environment
 LANGUAGE=en_US.UTF-8
 LANG=en_US.UTF-8
 LC_CTYPE=en_US.UTF-8
 LC_ALL=en_US.UTF-8

通过删除line export LANG=en_US。utf - 8

重新打开一个新标签和SSHed，为我工作:)

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:

将以下内容添加到/etc/environment中，为我解决了Debian和Ubuntu上的问题(当然，修改以匹配您想使用的语言环境):

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

Debian GNU/Linux 11(靶心)

我在GCP中创建一个全新的VM实例后遇到了这个问题。

基本上，我刚刚运行了以下程序

$ sudo apt-get update
$ sudo apt-get upgrade

这里我得到了错误

perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LC_CTYPE = "UTF-8",
LC_TERMINAL = "iTerm2",
LANG = "C"
are supported and installed on your system.

以下是我的解决方法。

首先安装区域设置。

$ sudo apt-get install locales

打开语言环境文件(使用您喜欢的编辑器)。

$ sudo nano /etc/default/locale

添加以下内容并保存。

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

执行以下命令。

$ sudo localedef -i en_US -f UTF-8 en_US.UTF-8

重新启动终端。 运行命令测试并通过ctrl + d关闭它。

$ perl

注意: 我创建了一个实例来测试我的解决方案，以确保。如果对你不起作用请告诉我。

我希望这对你有所帮助。
