如何解决使用 pyenv 创建隔离的 Jupyter ipython 内核：未找到模块 ipykernel_launcher
我花了几个小时在互联网上寻找修复方法，但仍然无法找到解决问题的方法。
我使用 pyenv 创建了一个名为“playground”的虚拟环境，并在其中安装了 ipykernel：
cd playground
user@Jerome-Ko-Jia-Jin playground % pip3 list

pyenv which python
/Users/user/.pyenv/versions/playground/bin/python
添加了具有以下内容的 kernel.json：
user@Jerome-Ko-Jia-Jin ~ % jupyter --paths
config:
/Users/user/.jupyter
/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/etc/jupyter
/usr/local/etc/jupyter
/etc/jupyter
data:
/Users/user/Library/Jupyter
/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/share/jupyter
/usr/local/share/jupyter
/usr/share/jupyter
runtime:
/Users/user/Library/Jupyter/runtime
user@Jerome-Ko-Jia-Jin ~ % jupyter --paths
config:
/Users/user/.jupyter
/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/etc/jupyter
/usr/local/etc/jupyter
/etc/jupyter
data:
/Users/user/Library/Jupyter
/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/share/jupyter
/usr/local/share/jupyter
/usr/share/jupyter
runtime:
/Users/user/Library/Jupyter/runtime
python -m ipykernel install --user --name playground --display-name "Playground"
cd /Users/user/Library/Jupyter/kernels/playground
user@Jerome-Ko-Jia-Jin playground % cat kernel.json
{
"argv": [
"/Users/user/.pyenv/versions/playground/bin/python","-m","ipykernel_launcher","-f","{connection_file}"
],"display_name": "Playground","language": "python"
}%
运行 Jupyter notebook 并切换到新的“Playground”内核，但出现此错误：
/Users/user/.pyenv/versions/playground/bin/python: No module named ipykernel_launcher
有人可以在这里启发我吗？我尝试重新安装 ipykernel 但它仍然不起作用。
在此先谢谢你:)
