问题解决办法
要想达到应用程序中正常显示中文字符的目的,要下面的三个变量应该如下,
1
2
3
LANG=zh_CN.UTF-8
LANGUAGE=zh_CN:zh:en_US:en
LC_ALL=LC_ALL=zh_CN.UTF-8
但问题在于“LC_ALL to default locale: No such file or directory”和“LC_ALL: cannot change locale (zh_CN.UTF-8) ”,因此重新安装中文语言包。
执行下面命令
1
sudoapt-get-yinstalllanguage-pack-zh-hans
或
1
sudoapt-get-yinstalllanguage-pack-zh-hanslanguage-pack-zh-hans-base
如果想支持繁体字,则执行
1
sudoapt-get-yinstalllanguage-pack-zh-hant
或
1
sudoapt-get-yinstalllanguage-pack-zh-hantlanguage-pack-zh-hant-base
再执行locale命令设置当前locale环境
1
locale
相关的文件和参考
相关手册:man locale(1), locale(5), locale(7)
相关文件:/usr/share/i18n/SUPPORTED
相关命令:
locale –all-locales 列出当前系统中所有支持的locale
localectl list-locales 列出当前系统中所有可用的locale
localectl set-locales LOCALE… 修改当前系统中的locale,与locale功能相同,与export上文提到的三个变量相同
对于CentOS,可以直接编辑/etc/sysconfig/i18n文件,将LANG=”en_US.UTF-8″设置成LANG=”zh_CN.UTF-8″,除此之外,CentOS下locale命令的显示结果如下:
1
#locale
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=
其中,LC_ALL=为空,但并不是表示这里不对,而是LC_ALL=实际上等于LC_COLLATE、LC_CTYPE、LC_MONETARY、LC_MESSAGES、LC_NUMERIC、LC_TIME,参见locale(7)。
