fr_FR.UTF-8 和 C.UTF-8 語言環境在語言環境列表中不可用，因此我無法使用它們

fr_FR.UTF-8和語言環境在C.UTF-8語言環境列表（由 給出locale -a）中不可用，因此我無法使用它們。

這是我嘗試添加它們的方法：

編輯 1：在我的系統上，locale-gen可以接受參數，因為它有點舊（包語言環境 v2.13）。

無論如何，涉及的其他方法/etc/locale.gen也不起作用：

$ cat <<-EOF | sudo tee -a /etc/locale.gen
en_US.UTF-8 UTF-8
en_US ISO-8859-1
en_US.ISO-8859-15 ISO-8859-15

fr_FR.UTF-8和語言環境在 . 給出的C.UTF-8語言環境列表中仍然不可用locale -a。

我該怎麼做？

請大家不要生我的氣:)

我終於找到了原因，我的 PATH 出了點問題：

$ ssh localhost locale -a >/dev/null
$ which -a locale
/home/linuxbrew/.linuxbrew/bin/locale
/usr/bin/locale
$ /home/linuxbrew/.linuxbrew/bin/locale -a >/dev/null 
/home/linuxbrew/.linuxbrew/bin/locale: Cannot set LC_CTYPE to default locale: No such file or directory
/home/linuxbrew/.linuxbrew/bin/locale: Cannot set LC_MESSAGES to default locale: No such file or directory
/home/linuxbrew/.linuxbrew/bin/locale: Cannot set LC_COLLATE to default locale: No such file or directory
$ /usr/bin/locale -a >/dev/null
$ /usr/bin/locale -a | egrep -i "(C|fr_FR|en_US).utf-?8"
C.UTF-8
en_US.utf8
fr_FR.utf8

locale-gen不接受任何命令行參數。相反，它讀取/etc/locale.gen要生成的語言環境列表。

編輯/etc/locale.gen以取消註釋您想要的語言環境，然後locale-gen再次執行。

或者，如果 中沒有註釋掉的行/etc/locale.gen，找到支持的語言環境列表並從那裡複製；在 Debian（以及可能的相關發行版）中，您可以在/usr/share/i18n/SUPPORTED.
