如何在 Raspbian 中設置 LC_ALL=en_GB.UTF-8？

我知道執行緒中的答案如何解決我的語言環境問題？，通過它我無法更改欄位LANGUAGE和LC_ALL相應的值。我正在我的最新作業系統 Raspberry Pi 3B Raspbian 中設置Retropie。我的locale

LANG=en_GB.UTF-8
LANGUAGE= # TODO empty! but should be en_GB:en
LC_CTYPE="en_GB.UTF-8"
LC_NUMERIC="en_GB.UTF-8"
LC_TIME="en_GB.UTF-8"
LC_COLLATE="en_GB.UTF-8"
LC_MONETARY="en_GB.UTF-8"
LC_MESSAGES="en_GB:UTF-8"
LC_PAPER="en_GB.UTF-8"
LC_NAME="en_GB.UTF-8"
LC_ADDRESS="en_GB.UTF-8"
LC_TELEPHONE="en_GB.UTF-8"
LC_MEASUREMENT="en_GB.UTF-8"
LC_IDENTIFICATION="en_GB.UTF-8"
LC_ALL= # TODO empty but should be en_GB.UTF-8

作業系統：Raspbian

硬體：Raspberry Pi 3B

編輯/etc/locale.gen然後取消註釋以下行：

en_GB.UTF-8 UTF-8

跑：

locale-gen en_GB.UTF-8 UTF-8
update-locale en_GB.UTF-8 UTF-8
export LANGUAGE=en_GB.UTF-8
export LC_ALL=en_GB.UTF-8

驗證它；locale：

LANG=en_GB.UTF-8
LANGUAGE=en_GB.UTF-8
LC_CTYPE="en_GB.UTF-8"
LC_NUMERIC="en_GB.UTF-8"
LC_TIME="en_GB.UTF-8"
LC_COLLATE="en_GB.UTF-8"
LC_MONETARY="en_GB.UTF-8"
LC_MESSAGES="en_GB.UTF-8"
LC_PAPER="en_GB.UTF-8"
LC_NAME="en_GB.UTF-8"
LC_ADDRESS="en_GB.UTF-8"
LC_TELEPHONE="en_GB.UTF-8"
LC_MEASUREMENT="en_GB.UTF-8"
LC_IDENTIFICATION="en_GB.UTF-8"
LC_ALL=en_GB.UTF-8
