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 , 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)：
