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

将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，如果出现下列错误，说明没安装en\_US的local ``` pi@raspberry:~$ 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 ``` 查看系统内安装的locale ``` pi@raspberry:~$ 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 ``` 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。
