把语言环境变量改为英文

将Ubuntu系统语言环境改为英文的en_US.UTF-8

查看当前系统语言环境

locale

编辑配置文件，将zh_US.UTF-8改为en_US.UTF-8，zh改为en

sudo nano /etc/default/locale

LANG="en_US.UTF-8"

LANGUAGE="en_US:en"

继续查看更改后的系统语言变量，假设出现下列错误。说明没安装en_US的local

qii@ubuntu:~$ locale

locale: Cannot set LC_CTYPE to default locale: No such file or directory

locale: Cannot set LC_MESSAGES to default locale: No such file or directory

locale: Cannot set LC_ALL to default locale: No such file or directory

LANG=en_US.UTF-8

LANGUAGE=en_US:en

LC_CTYPE="en_US.UTF-8"

LC_NUMERIC="en_US.UTF-8"

LC_TIME="en_US.UTF-8"

LC_COLLATE="en_US.UTF-8"

LC_MONETARY="en_US.UTF-8"

LC_MESSAGES="en_US.UTF-8"

LC_PAPER="en_US.UTF-8"

LC_NAME="en_US.UTF-8"

LC_ADDRESS="en_US.UTF-8"

LC_TELEPHONE="en_US.UTF-8"

LC_MEASUREMENT="en_US.UTF-8"

LC_IDENTIFICATION="en_US.UTF-8"

LC_ALL=

查看系统内安装的locale

qii@ubuntu:~$ locale -a

locale: Cannot set LC_CTYPE to default locale: No such file or directory

locale: Cannot set LC_MESSAGES to default locale: No such file or directory

locale: Cannot set LC_COLLATE to default locale: No such file or directory

C

POSIX

zh_CN.utf8

zh_SG.utf8

看吧。没装en_US.UTF-8

安装en_US.UTF-8

sudo locale-gen en_US.UTF-8

再次查看，应该一切正常了。
