在Ubuntu Server 12.04上执行apt-get install命令时，报如下warning
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = "zh_CN:zh", LC_ALL = (unset), LC_TIME = "zh_CN", LC_MONETARY = "zh_CN", LC_ADDRESS = "zh_CN", LC_TELEPHONE = "zh_CN", LC_NAME = "zh_CN", LC_MEASUREMENT = "zh_CN", LC_IDENTIFICATION = "zh_CN", LC_NUMERIC = "zh_CN", LC_PAPER = "zh_CN", LANG = "zh_CN.UTF-8" are supported and installed on your system. 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 |
搜了一下解决办法，参考这篇文章，在家目录下
在文件尾加入
保存后执行
问题解决。
为什么这么做？
看了这篇文章了解了下locale，上面报的warning意思大概可以归纳为
- LC_ALL变量的值unset
- LC_CTYPE和LC_MESSAGES的值设置的可能有问题
先将原来添加到.bashrc中的“export LC_ALL=C”删除，重启客户端会话，恢复系统到一开始的状态
su到root查看系统locale设置
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
$ su - root # 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= |
查看系统已安装的locale
|
|
# 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_US.utf8 zh_CN zh_CN.gb2312 |
定位错误为 (1) LC_ALL没设置值，(2) LC_CTYPE和LC_MESSAGES的值zh_CN.UTF-8系统未安装
1、设置LC_ALL的值为zh_CN.UTF-8
2、执行
|
|
# cd /usr/share/locales # ./install-language-pack zh_CN |
安装这个locale
问题解决。
正如这篇文章所说，LC_ALL的优先级最高，所以不执行步骤1只执行步骤2就可以解决问题。另外，为了避免locale设置成zh_CN可能带来的稀奇古怪的错误，我直接将/etc/default/locale文件从这样
|
|
LANG="zh_CN.UTF-8" LANGUAGE="zh_CN:zh" LC_NUMERIC="zh_CN" LC_TIME="zh_CN" LC_MONETARY="zh_CN" LC_PAPER="zh_CN" LC_NAME="zh_CN" LC_ADDRESS="zh_CN" LC_TELEPHONE="zh_CN" LC_MEASUREMENT="zh_CN" LC_IDENTIFICATION="zh_CN" |
设置成这样
|
|
LANG="zh_CN.UTF-8" LANGUAGE="zh_CN:zh" LC_NUMERIC="zh_CN.UTF-8" LC_TIME="zh_CN.UTF-8" LC_MONETARY="zh_CN.UTF-8" LC_PAPER="zh_CN.UTF-8" LC_NAME="zh_CN.UTF-8" LC_ADDRESS="zh_CN.UTF-8" LC_TELEPHONE="zh_CN.UTF-8" LC_MEASUREMENT="zh_CN.UTF-8" LC_IDENTIFICATION="zh_CN.UTF-8" |
