安装最新的Mac OSX 64 位 Anaconda Python 发行版后，我在尝试启动 IPython Notebook 时不断收到 ValueError。

启动 ipython 工作正常：

3-millerc-~:ipython
Python 2.7.3 |Anaconda 1.4.0 (x86_64)| (default, Feb 25 2013, 18:45:56) 
Type "copyright", "credits" or "license" for more information.

IPython 0.13.1 -- An enhanced Interactive Python.
?         -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help      -> Python's own help system.
object?   -> Details about 'object', use 'object??' for extra details.

但启动 ipython 笔记本：

4-millerc-~:ipython notebook

导致 ValueError （带回溯）：

从终端运行locale命令：

5-millerc-~:locale 
LANG=
LC_COLLATE="C"
LC_CTYPE="UTF-8"
LC_MESSAGES="C"
LC_MONETARY="C"
LC_NUMERIC="C"
LC_TIME="C"
LC_ALL=

我在这里总结了解决方案：http ://blog.lobraun.de/2009/04/11/mercurial-on-mac-os-x-valueerror-unknown-locale-utf-8/

我将这些行添加到我的.bash_profile：

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

我重新加载了配置文件：

source ~/.bash_profile

然后我又跑ipython了：

ipython notebook

更改语言环境

以上将适用于美国语言环境中的英语。可能需要不同的设置。

冒着明显的风险，要发现系统的当前设置，请使用：

$ locale

并检索系统上所有有效设置的列表：

$ locale -a

然后选择您喜欢的语言环境。例如，对于瑞士法语语言环境，解决方案如下所示：

export LC_ALL=fr_CH.UTF-8
export LANG=fr_CH.UTF-8

这是 OS X 终端应用程序中的一个错误，仅在某些区域设置（国家/语言组合）中出现。在 /Applications/Utilities 中打开终端并取消选中“启动时设置区域环境变量”框。

在此处输入图像描述

这会将您的LANG环境变量设置为空。这可能会导致终端使用不正确的区域设置。终端中的 locale 命令将告诉您使用了哪些设置。要使用正确的语言，请在 bash 配置文件中添加一行（通常为~/.profile）

export LANG=your-lang

替换your-lang为您的语言的正确语言环境说明符。该命令locale -a将向您显示所有说明符。例如，美国英语的语言代码是en_US.UTF-8. 语言环境会影响可用时使用的翻译，以及日期、货币和小数的格式。

请注意，此图像和内容取自http://conda.pydata.org/docs/troubleshooting.html#unknown-locale（我也是该页面的原作者）。

在 iTerm 中进入菜单

Preferences -> Profiles -> Terminal -> (Environment)

然后取消选中

"Set locale variables automatically"

使这个错误消失了。

由于您LC_CTYPE的错误，您应该找出错误值的设置位置并将其更改为类似en_US.UTF-8.
