安装“jupyter-markdown”扩展后无法加载 Jupyter Lab

问：

我刚刚通过安装了 Jupyter Lab。它运行良好，直到我通过 .pip installpip install jupyter-markdown

现在我无法加载 Jupyter Lab。我收到以下错误：

我可以删除虚拟环境并重新创建 venv 并重新安装 Jupyter Lab。我的问题是知道是否有办法安装“jupyter-markdown”扩展并在 Jupyter Lab 中使用它。如果我通过 Jupyter Lab 扩展选项卡安装扩展，我会收到同样的错误。jupyter-markdown

我使用 Windows 11、python 3.11.0
