debian10 修改系統語言

(1) 更新軟件包列表 apt-get update

(2）安裝locales包，apt-get install -y locales。安裝完成后會自動生產/etc/locale.gen

(3) 去掉/etc/locale.gen文件中zh_CN.UTF-8所在行前面的注釋，sed -i 's/^# *\(zh_CN.UTF-8\)/\1/' /etc/locale.gen
(4) 運行locale-gen命令
(5) 在~/.bashrc中設置LC_ALL、LANG、LANGUAGE
　　echo "export LC_ALL=zh_CN.UTF-8" >> ~/.bashrc \
　　echo "export LANG=zh_CN.UTF-8" >> ~/.bashrc \
　　echo "export LANGUAGE=zh_CN.UTF-8" >> ~/.bashrc

(6) source ~/.bashrc
