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/
我在这里总结了可以在以下位置找到的解决方案：http: //blog.lobraun.de/2009/04/11/mercurial-on-mac-os-x-valueerror-unknown-locale-utf-8/
I added these lines to my .bash_profile:
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
I reloaded the profile:
我重新加载了配置文件：
source ~/.bash_profile
I then ran ipythonagain:
然后我又跑ipython了：
ipython notebook
Changing locales
更改语言环境
The above will work for the English language in a US locale. One may want different settings.
以上将适用于美国语言环境中的英语。人们可能需要不同的设置。
At the risk of stating the obvious, to discover the current settings for your system, use:
冒着说明明显的风险，要发现系统的当前设置，请使用：
$ locale
And to retrieve a list of all valid settings on your system:
并检索系统上所有有效设置的列表：
$ locale -a
Then choose your preferred locale. For example, for a Swiss French locale, the solution would look like this:
然后选择您喜欢的语言环境。例如，对于瑞士法语语言环境，解决方案如下所示：
export LC_ALL=fr_CH.UTF-8
export LANG=fr_CH.UTF-8
回答by wRAR
As your LC_CTYPEis wrong, you should find out where that wrong value is set and change it to something like en_US.UTF-8.
由于您LC_CTYPE错了，您应该找出错误值的设置位置并将其更改为类似en_US.UTF-8.

This is a bug in the OS X Terminal app that only shows up in certain locales (country/language combinations). Open Terminal in /Applications/Utilities and uncheck the box “Set locale environment variables on startup”.
这是 OS X 终端应用程序中的一个错误，仅在某些区域设置（国家/语言组合）中出现。在 /Applications/Utilities 中打开终端并取消选中“启动时设置区域设置环境变量”框。
This will set your LANGenvironment variable to be empty. This may cause terminal use to incorrect settings for your locale. The locale command in the Terminal will tell you what settings are used. To use the correct language, add a line to your bash profile (typically ~/.profile)
这会将您的LANG环境变量设置为空。这可能会导致终端使用您的区域设置不正确。终端中的 locale 命令会告诉您使用了哪些设置。要使用正确的语言，请在您的 bash 配置文件中添加一行（通常为~/.profile）
export LANG=your-lang
Replace your-langwith the correct locale specifier for your language. The command locale -awill show you all the specifiers. For example, the language code for US English is en_US.UTF-8. The locale affects what translations are used when they are available, and also how dates, currencies, and decimals are formatted.
替换your-lang为您的语言的正确区域设置说明符。该命令locale -a将向您显示所有说明符。例如，美国英语的语言代码是en_US.UTF-8。区域设置会影响可用时使用的翻译，以及日期、货币和小数的格式。

in iTerm going to the menu
在 iTerm 中转到菜单
Preferences -> Profiles -> Terminal -> (Environment)
and then unchecking
然后取消选中
"Set locale variables automatically"
made this error go away.
使这个错误消失了。
