IPython笔记本区域设置错误

安装最新的Mac OSX 64位Anaconda Python发行版之后 ，在尝试启动IPython Notebook时，我不断收到一个ValueError。

开始ipython正常工作：

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. 

但是启动ipython笔记本：

 4-millerc-~:ipython notebook 

ValueError中的结果（带回溯）：

从terminal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= 

Answer 1

我总结这里的解决scheme： 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configuration文件：

 source ~/.bash_profile 

然后我再次运行ipython ：

 ipython notebook 

更改区域设置

以上内容适用于美国地区的英语。 人们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select您的首选区域设置。 例如，对于瑞士法语区域，解决scheme将如下所示：

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

Answer 2

这是OS X Terminal应用程序中的一个错误，只显示在某些语言环境（国家/语言组合）中。 在/ Applications / Utilities中打开terminal，取消勾选“启动时设置语言环境variables”。

这将设置您的LANG环境variables为空。 这可能会导致terminal使用不正确的设置为您的区域设置。 terminal中的locale命令会告诉你使用了什么设置。 要使用正确的语言，请将一行添加到您的bashconfiguration文件（通常为~/.profile ）

 export LANG=your-lang 

将your-langreplace为您的语言的正确语言环境说明符。 命令locale -a将显示所有的说明符。 例如，美国英语的语言代码是en_US.UTF-8 。 语言环境会影响翻译的可用时间，以及date，货币和小数位的格式。

Answer 3

在iTerm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。

Answer 4

由于你的LC_CTYPE是错误的，你应该找出错误值设置的位置，并将其改为en_US.UTF-8 。
