man 给出了有关区域设置的错误

我有

$ locale
LANG=en_GB.UTF-8
LC_CTYPE=ru_RU.UTF-8
LC_NUMERIC=en_GB.UTF-8
LC_TIME=en_GB.UTF-8
LC_COLLATE=ru_RU.UTF-8
LC_MONETARY=ru_RU.UTF-8
LC_MESSAGES=en_GB.UTF-8
LC_PAPER=ru_RU.UTF-8
LC_NAME=ru_RU.UTF-8
LC_ADDRESS=ru_RU.UTF-8
LC_TELEPHONE=ru_RU.UTF-8
LC_MEASUREMENT=ru_RU.UTF-8
LC_IDENTIFICATION="en_GB.UTF-8"
LC_ALL=

$ locale -a
C
en_GB.utf8
POSIX
ru_RU.utf8

但man给出了错误：

$ man
man: can't set the locale; make sure $LC_* and $LANG are correct
What manual page do you want?

如果我设置LC_ALL，错误就会消失：

$ LC_ALL=en_GB.UTF-8 man
What manual page do you want?

但我不想设置，LC_ALL因为我将一些设置LC_为其他语言环境。

如何解决这个问题man？

答案1

man我在Debian squeeze 的源代码中找到了这段代码：

/* initialise the locale */
    if (!setlocale (LC_ALL, "") && !getenv ("MAN_NO_LOCALE_WARNING"))
        /* Obviously can't translate this. */
        error (0, 0, "can't set the locale; make sure $LC_* and $LANG "
                 "are correct");
    setenv ("MAN_NO_LOCALE_WARNING", "1", 1);

尝试将环境变量设置MAN_NO_LOCALE_WARNING为 1 看看是否有帮助。setlocale (LC_ALL, "")根据以下文档，我不确定为什么失败setlocale()：

The return value is NULL if the request cannot be honored.
