如何升级kernmagic以修复此ipython错误？

Question

我最近升级了我的Enthought Python发行版

sudo easy_install -U ipython

但是,当我用ipython命令启动ipython时,我收到一个错误:

AttributeError: 'TerminalInteractiveShell' object has no attribute 'shell'

我google了,我发现很多帖子都说在ipython配置文件中注释掉这一行.

c.TerminalIPythonApp.extensions = ['kernmagic']

我发现注释掉一个ipython文件是很粗略的......后来,我发现用ipython kernmagic 解决了这个问题.

如何kernmagic在我的ipython发行版中升级以便此错误消失？

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
