Question

我在Mac上安装了带有Python 3内核的jupyter笔记本。我尝试使用命令python2 -m pip install ipykernel安装Python 2内核，但出现以下错误：

Collecting ipykernel

有谁能告诉我问题出在哪里以及如何为python 2安装内核？

Answer 1

假设您正在运行Anaconda，我认为在您的终端中输入以下命令可能有效

1）使用创建Python 2.7 conda env

conda create -n python2 python=2.7

2）从终端激活你的新环境。

source activate python2

3）将ipykernel安装到python2 env

中

pip install ipykernel

4）将python2内核安装到ipython

中

ipython kernel install --name python2

如果您没有运行Anaconda，请尝试本教程; Create isolated Jupyter ipython kernels with pyenv and virtualenv
