这个问题已经在这里有了答案：

Pelican 3.3 pelican-quickstart错误“ ValueError：未知语言环境：UTF-8” 6个答案

安装最新的Mac OSX 64位Anaconda Python发行版之后，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)：
