[root@iZ2ze3n2wuzr91sx0vgwwdZ ~]# locale locale: Cannot set LC_ALL to default locale: No such file or directory LANG=en_US.UTF-8 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=

 

发现一个错误信息：locale: Cannot set LC_ALL to default locale: No such file or directory

为了解决这个问题，要设置 LC_ALL 的参数，

[root@iZ2ze3n2wuzr91sx0vgwwdZ ~]# export LC_ALL="en_US.UTF-8" -bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8) -bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)

　　执行这个命令也发生了 warning，再次执行 locale 命令，错误信息依然存在，但 LC_ALL 已经有值了，但与其他参数不同的是没有双引号，看来依然不对。

[root@iZ2ze3n2wuzr91sx0vgwwdZ ~]# locale locale: Cannot set LC_ALL to default locale: No such file or directory LANG=en_US.UTF-8 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=en_US.UTF-8

　　

　　继续执行命令：sudo localedef -i en_US -f UTF-8 en_US.UTF-8

　　这个命令执行成功了，在使用 locale 验证一下，问题解决。
