在Ubuntu安装完成后更改默认的语言LANG

在安装ubuntu的时候选了中文，但后来发现SVN客户端需要utf8来支持中文。

于是修改 /etc/default/locale为：

LANG="en_US.UTF-8"
LANGUAGE="en_US:en"



但是，后来perl, locale,export LANG=en_US.UTF-8之类的命令都出现warning：

> 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=en_US.UTF-8
LANGUAGE=en_US:en
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=



解决办法：

locale-gen en_US.UTF-8
