快速旁注：
这个问题基于问题#7947 inipython的错误跟踪器。该问题似乎与OSX我的 mac 上的任何一个或一些奇怪的设置有关（可能两者兼而有之）。我无法在新的 Ubuntu 机器上重现它。
我知道潜在的问题可能很复杂。知道它是否可以重现OSX或者只是我自己已经是一个很大的帮助。
我正在尝试jupyter为我的 python 版本设置多个内核。具体来说，我有两个conda环境sci27，sci34正如名称已经暗示的那样，前者运行python2.7解释器，后者运行解释python3.4器。
所以我现在要做的是：
source activate sci27
conda install ipython-notebook
ipython kernelspec install-self
现在我有我的内核定义/usr/local/share/jupyter/kernels/python2/
{
"display_name": "Python 2",
"language": "python",
"argv": [
"/Users/ch/miniconda/envs/sci27/bin/python",
"-m",
"IPython.kernel",
"-f",
"{connection_file}"
]
}
我从ipython我的sci34环境开始：
source activate sci34
conda install ipython-notebook
ipython notebook --debug
现在事情变得很奇怪：如果我选择新安装Python 2的内核，内核会崩溃并显示以下输出：

这个消息/Users/ch/miniconda/envs/sci34/bin/python: No module named IPython对我来说是相当令人惊讶的。为什么会jupyter尝试调用sci34' 解释器而不是sci27' 解释器？
另外，为什么要module not found留言？显然/Users/ch/miniconda/envs/sci34/bin/python -m IPython工作得很好，因为笔记本服务器从sci34环境中运行。
