在Linux下使用locale命令提示如下警告：

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


然后，我使用locale -a命令查看了系统安装的字符编码：


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 C.UTF-8 POSIX en_US.utf8 zh_CN zh_CN.gb2312


发现问题是，我系统上设置的是字符编码是zh_CN.UTF-8，而系统并没有安装zh_CN.UTF-8字符编码。


解决方案：

使用sudo locale-gen zh_CN.UTF-8安装该编码类型，问题解决。







下面说说，怎么在命令行修改字符编码，这里讲中文修改为英文。

1. 编辑配置文件，将zh_CN.UTF-8改为en_US.UTF-8，zh_CN改为en_US。


sudo vim /etc/default/locale


:%s/zh_CN/en_US/g


2. 使用sudo locale-gen en_US.UTF-8命令重新编译该字符编码。



跟系统字符编码设置有关的另一个问题：ls: error initializing month strings

解决方法：sudo vim /etc/default/locale

LANG="zh_CN.UTF-8"
LANGUAGE="zh_CN:zh"
LC_NUMERIC="zh_CN.UTF-8"
LC_TIME="zh_CN.UTF8"

红色部分保证后面带有 .UTF-8
