Question

快速注释：

此问题基于ipython的错误跟踪器中的问题#7947。问题似乎是与OSX相关的问题，或者我的mac上的一些奇怪的设置（可能两者）。我无法在新的Ubuntu盒子上重现它。

我知道潜在的问题可能很复杂。知道它是否可以在OSX上重现，或者它是否只是我的帮助。

我正在尝试为我的python版本设置多个jupyter内核。具体来说，我有两个conda环境sci27和sci34，因为名称已经建议前者运行python2.7解释器，后者运行python3.4解释器。

所以我现在所做的是：

source activate sci27
conda install ipython-notebook
ipython kernelspec install-self

现在我在/usr/local/share/jupyter/kernels/python2/

中有我的内核定义

{
 "display_name": "Python 2",
 "language": "python",
 "argv": [
  "/Users/ch/miniconda/envs/sci27/bin/python",
  "-m",
  "IPython.kernel",
  "-f",
  "{connection_file}"
 ]
}

我在ipython环境中启动sci34：

source activate sci34
conda install ipython-notebook
ipython notebook --debug

现在事情变得很奇怪：如果我选择新安装的内核Python 2，内核会崩溃并输出以下内容：

消息/Users/ch/miniconda/envs/sci34/bin/python: No module named IPython让我感到惊讶。为什么jupyter会尝试拨打sci34的翻译而不是sci27的翻译？

另外，为什么module not found消息？显然/Users/ch/miniconda/envs/sci34/bin/python -m IPython工作正常，因为笔记本服务器从sci34环境运行。

更新到IPython 3.2.0将解决此问题。有关详细信息，请参阅提取请求PR-8527。
