Ubuntu下locale命令路径无法找到问题解决方法：Cannot set LC_CTYPE to default locale: No such file or directory

今天在Ubuntu上安装一些依赖包的时候遇到了locale命令提示路径无法找到的问题。具体如下：

perl: warning: Falling back to the standard locale ("C").
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
/usr/bin/locale: Cannot set LC_CTYPE to default locale: No such file or directory
/usr/bin/locale: Cannot set LC_MESSAGES to default locale: No such file or directory
/usr/bin/locale: Cannot set LC_ALL to default locale: No such file or directory

直接使用locale命令提示如下：

root@ubuntu:/home# 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=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=

然后使用locale -a 命令查看系统安装的字符编码：

root@ubuntu:/home/yao# 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
C.UTF-8
POSIX
en_AG
en_AG.utf8
en_AU.utf8
en_BW.utf8
en_CA.utf8
en_DK.utf8
en_GB.utf8
en_HK.utf8
en_IE.utf8
en_IN
en_IN.utf8
en_NG
en_NG.utf8
en_NZ.utf8
en_PH.utf8
en_SG.utf8
en_US.utf8
en_ZA.utf8
en_ZM
en_ZM.utf8
en_ZW.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：

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

/2

2、修改配置文件，将zh_CN.UTF-8改为en_US.UTF-8，zh_CN改为en_US。

sudo vim /etc/default/locale

将文档中所有zh_CN字符替换为en_US

:%s/zh_CN/en_US/g

3、至此问题已经解决，下面我们验证一下，如下面所示，通过locale命令时，已不再提示“No such file or directory”

root@ubuntu:/home# locale
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"
