如何升级kernmagic以修复此ipython错误？ [英] How do I upgrade kernmagic to fix this ipython error?

问题描述

我最近升级了我的Enthought Python发行版

I recently upgraded my Enthought Python distribution with

sudo easy_install -U ipython

但是，当我使用 ipython 命令启动ipython时，出现错误：

However, when I start up ipython with the ipython command, I get an error:

我google了一下，我找到的很多帖子都说明了这一行一个ipython配置文件。

I googled around, and many posts I found said to comment out this line in an ipython configuration file.

c.TerminalIPythonApp.extensions = ['kernmagic']

我发现注释掉一个ipython文件是很粗略的......后来，我发现 kernmagic 使用ipython 解决了问题。

I find it sketchy to comment out an ipython file though... later, I found that kernmagic fixed the issue with ipython.

如何在我的ipython发行版中升级 kernmagic 以便此错误消失？

How do I upgrade kernmagic in my ipython distribution so that this error goes away?

推荐答案

这对我有用：

hg clone https://bitbucket.org/robertkern/kernmagic
cd kernmagic
python setup.py build
python -c "import setuptools;execfile('setup.py')" bdist_egg
egginst dist/kernmagic-0.0.0-py2.7.egg
