使用pyenv创建隔离的Jupyter-ipython内核：未找到模块ipykernel\u启动器

我花了几个小时在互联网上寻找解决办法，但仍然找不到解决问题的办法

我使用

pyenv

创建了一个名为“游乐场”的虚拟env，并在以下位置安装了

ipykernel

：

cd playground

user@Jerome-Ko-Jia-Jin playground % pip3 list

pyenv which python
/Users/user/.pyenv/versions/playground/bin/python

添加了kernel.json和以下内容：

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

    /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笔记本并切换到新的“游乐场”内核，但我发现以下错误：

/Users/user/.pyenv/versions/playerly/bin/python:没有名为ipykernel\u启动器的模块

有人能在这里给我指点一下吗？我尝试重新安装了ipykernel，但仍然不起作用

提前非常感谢：）
