IPython Notebook语言环境错误 [英] IPython Notebook locale error

问题描述

安装最新的 Mac OSX 64位Anaconda Python发行版后，我在尝试时遇到了ValueError启动IPython笔记本。

After installing the latest Mac OSX 64-bit Anaconda Python distribution, I keep getting a ValueError when trying to start the IPython Notebook.

启动ipython工作正常：

Starting ipython works fine:

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：

But starting ipython notebook:

4-millerc-~:ipython notebook

导致ValueError（跟踪）：

Results in the ValueError (with traceback):

运行<来自终端的code> 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=

推荐答案

我在这里总结一下可以找到的解决方案： http://blog.lobraun.de/2009/04/11/mercurial-on-mac-os-x-valueerror-unknown-locale-ut f-8 /

I summarize here the solution to be found on: 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 ：

I added these lines to my .bash_profile:

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

我重新加载了个人资料：

I reloaded the profile:

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语言环境中的英语语言。人们可能需要不同的设置。

Changing locales

The above will work for the English language in a US locale. One may want different settings.

冒着明显的风险，要发现系统的当前设置，请使用：

At the risk of stating the obvious, to discover the current settings for your system, use:

$ locale

并检索清单系统上所有有效设置：

And to retrieve a list of all valid settings on your system:

$ locale -a

然后选择您喜欢的语言环境。例如，对于瑞士法语区域设置，解决方案如下所示：

Then choose your preferred locale. For example, for a Swiss French locale, the solution would look like this:

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