Jupyter 无法识别 Python Mac OSX（内核错误）

Question

我用 Anaconda 安装了 python 3.6，但是在启动 jupyter notebook 后我无法使用 python。

当我启动一个新笔记本时，我在页面顶部看到“内核错误”，其中包含以下几行：

 Traceback (most recent call last):

我猜最后一行是解决这个问题的关键，但我也没有找到任何与之相关的解决方案。

有什么想法吗？

Answer 1

我终于找到了解决办法：

export PATH=~/anaconda3/bin:$PATH
conda create -n py33 python=3.6 anaconda
source activate py33
python -m ipykernel install --user
