Question

Jupyter实验室退出工作了，我无法重新启动它。
操作系统：赢10
jupyterlab版本：2.2.8
python版本：3.8
浏览器：最新的Chrome

错误是显示了jupyter-lab窗口，但显示如下：载入中... 载入画面需要很长时间。您要清理工作区还是继续等待？保持等待-或-清除工作区

如果我选择“保持等待”：jupyter实验室窗口不会激活。如果我选择“清除工作空间”：jupyter实验室窗口仅会以相同的错误消息重新启动。

当我尝试启动Jupyter Lab时的cmd结果：

c:\Users\champ\Python_proj>jupyter lab --port 8889 [W 21:57:09.947 LabApp] Error loading server extension jupyter_nbextensions_configurator

    Or copy and paste one of these URLs:

我尝试过：

重新启动操作系统
已卸载并重新安装了jupyter lab
已运行jupyter笔记本。 Jupyter笔记本正在运行，但是我无法运行任何内核或访问任何文件夹。
已尝试禁用jupyter_nbextensions_configurator 我认为这不是主要问题，因为我总是会遇到此错误。
我看到端口8888不可用，因此我在端口8889上启动它。但是同样的错误信息。

如果我可以提供有关此问题的更多信息，请告诉我。
