xxx@kd:~/$locale locale: Cannot set LC_CTYPE to default locale: No such file or directory locale: Cannot set LC_MESSAGES to default locale: No such file or directory locale: Cannot set LC_ALL to default locale: No such file or directory LANG=zh_CN.UTF-8LANGUAGE=zh_CN:zh LC_CTYPE=zh_CN.utf8 LC_NUMERIC=zh_CN LC_TIME=zh_CN LC_COLLATE="zh_CN.UTF-8"LC_MONETARY=zh_CN LC_MESSAGES="zh_CN.UTF-8"LC_PAPER=zh_CN LC_NAME=zh_CN LC_ADDRESS=zh_CN LC_TELEPHONE=zh_CN LC_MEASUREMENT=zh_CN LC_IDENTIFICATION=zh_CN LC_ALL=
上面的输出显示LC_CTYPE,LC_MESSAGES,LC_ALL不能设置，前两个对应的值是zh_CN.utf8,zh_CN.UTF-8
那么我们只需要locale-gen对应的值就行
xx@kd:~/$sudo locale-gen zh_CN.UTF-8Generating locales... zh_CN.UTF-8... doneGeneration complete.
注：zh_CN.utf8和zh_CN.UTF-8是相同的值我们只需产生其中一个就行；LC_ALL是空值，当其他的值都设置好以后就不会出问题了
