目标

创建了一个新的conda环境，想要在jupyter notebook中也使用这个环境，记为目标环境

步骤

打开conda环境
激活目标conda环境
在目标conda环境中安装 ipykernel

conda list ipykernel

将目标conda环境注入Jupyter Notebook

python -m ipykernel install --user --name [your_env_name] n --display-name "[your_env_name]"

打开Jupyter Notebook，可以看到多了目标环境

调试

第四步报错：

操作：

pip uninstall -y ipython prompt_toolkit
pip install ipython prompt_toolkit

报错结果如下：
