安装最新的Mac OSX 64位Anaconda Python发行版后，尝试启动IPython Notebook时，我始终收到ValueError。

启动ipython可以正常工作：

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

结果出现ValueError（带有回溯）：

ValueError: unknown locale: UTF-8

locale从终端运行命令：

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=

回答：

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

我重新加载了个人资料：

source ~/.bash_profile

然后我又跑ipython了：

ipython notebook

以上内容适用于美国语言环境中的英语。可能需要不同的设置。

为了发现明显的风险，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

然后选择你首选的语言环境。例如，对于瑞士法语区域设置，解决方案如下所示：

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

以上是 IPython Notebook语言环境错误 的全部内容， 来源链接： utcz.com/qa/402500.html
