python - Conda 解决安装 `xeus-cling`

问题描述

我的终端在不安装xeus-cling软件包的情况下继续运行。我已经坚持了2个多小时了。

解决方案

该软件包用于 Jupyter 中的 C++ 内核支持。Jupyter + Conda 更惯用的做法是将 Jupyter 和每个内核保持在单独的环境中。

Jupyter 环境

conda create -n jupyter jupyter nb_conda_kernels

C++ 内核

conda create -n xeus xeus-cling

在此设置中，总是会从激活的环境中启动 Jupyter jupyter，然后xeus为笔记本选择内核。

conda activate jupyter
jupyter notebook
