MongoDB mongorestore failure: locale::facet::_S_create_c_locale name not valid
提问by Luca Anceschi
I created a dump with mongodump on computer A (ubuntu 12.04 server). I moved it to computer B (ubuntu 12.04 server) and typed:
我在计算机 A（ubuntu 12.04 服务器）上用 mongodump 创建了一个转储。我将它移到计算机 B（ubuntu 12.04 服务器）并输入：
mongorestore -db db_name --drop db_dump_path
mongorestore -db db_name --drop db_dump_path
It failed and it reported:
它失败了，并报告：
connected to: 127.0.0.1
terminate called after throwing an instance of 'std::runtime_error'
what(): locale::facet::_S_create_c_locale name not valid
Aborted
连接到：127.0.0.1
在抛出“std::runtime_error”
what()实例后调用终止：locale::facet::_S_create_c_locale 名称无效
中止
I've successfully accomplished this operation before and this strange behavior has never occurred. What do I need to do to fix this?
我之前已经成功完成了这个操作，从来没有发生过这种奇怪的行为。我需要做什么来解决这个问题？

Actually it isn't strictly related to MongoDB. Somehow the language on computer B was not defined correctly. I managed to fix it by typing:
实际上它与MongoDB没有严格的关系。不知何故，计算机 B 上的语言定义不正确。我设法通过键入来修复它：
sudo locale-gen en_US en_US.UTF-8
sudo locale-gen it_IT it_IT.UTF-8
sudo locale-gen xx_xx xx_XX.UTF-8 ...
sudo dpkg-reconfigure locales
sudo locale-gen en_US en_US.UTF-8
sudo locale-gen it_IT it_IT.UTF-8
sudo locale-gen xx_xx xx_XX.UTF-8 ...
sudo dpkg-reconfigure locales
These commands will generate and configure the needed locales. After those steps mongorestore got back working as usual.
这些命令将生成和配置所需的语言环境。在这些步骤之后 mongorestore 恢复正常工作。

On my distro "locale-gen" was not installed and it turned out all I had to do is set the LC_ALL environment variable. so the following command fixed it:
在我的发行版上没有安装“locale-gen”，结果我要做的就是设置 LC_ALL 环境变量。所以以下命令修复了它：
export LC_ALL="en_US.UTF-8"
hopefully it will help someone else...
希望它会帮助别人......

Exporting LC_ALL="en_US.UTF-8"only works if you have the en_USlocale installed. If you want to avoid installing the localespackage (or its equivalent on distributions other than Debian derivatives), then you can instead use:
LC_ALL="en_US.UTF-8"仅当您安装了en_US语言环境时，导出才有效。如果您想避免安装该locales软件包（或在 Debian 衍生版以外的发行版上的等价物），那么您可以改为使用：
export LC_ALL=C.UTF-8
which will not require any extra locale data.
这不需要任何额外的语言环境数据。

If you are using a Mac OSX and SSH this might be issued by wrong LC_CTYPE.
如果您使用的是 Mac OSX 和 SSH，这可能是由错误的 LC_CTYPE 发出的。
$ locale
locale: Cannot set LC_CTYPE 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=
LC_CTYPE=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=
Unset the wrong var.
取消设置错误的变量。
$ unset LC_CTYPE
Check whether locale is working fine.
检查语言环境是否工作正常。
$ locale
LANG=en_US.UTF-8
LANGUAGE=
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=
Now mongo also should do fine.
现在 mongo 也应该做得很好。

To make the fix permanent you can edit one of those files:
要使修复永久化，您可以编辑这些文件之一：
- sudo vim /etc/default/locale
- sudo vim /etc/environment
- 须藤vim /etc/default/locale
- 须藤vim /etc/environment
And add the line LC_ALL="en_US.UTF-8"
并添加行 LC_ALL="en_US.UTF-8"
