jupyter-notebook - Jupyter 实验室无法启动

问题描述

Jupyter 实验室停止工作，我无法重新开始。
操作系统：win 10
jupyterlab 版本：2.2.8
python 版本：3.8
浏览器：最新的 Chrome

错误是 jupyter-lab 窗口显示但显示如下：正在加载...加载屏幕需要很长时间。您想清空工作区还是继续等待？继续等待 - 或 - 清除工作区

如果我选择“继续等待”：jupyter 实验室窗口不会激活。如果我选择“清除工作区”：jupyter 实验室窗口只会以相同的错误消息重新启动。

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

    To access the notebook, open this file in a browser:
        file:///C:/Users/champ/AppData/Roaming/jupyter/runtime/nbserver-3700-open.html
    Or copy and paste one of these URLs:
        http://localhost:8889/?token=
     or http://127.0.0.1:8889/?token= [I 21:57:14.415 LabApp] 301 GET /lab/workspaces/auto-y/?clone (::1)

我努力了：

重新启动操作系统
已卸载并重新安装了 jupyter lab
已经运行了 jupyter notebook。Jupyter notebook 正在运行，但我无法运行任何内核或访问任何文件夹。
尝试禁用 jupyter_nbextensions_configurator 我不认为这是主要问题，因为我总是有这个错误。
我看到端口 8888 不可用，所以我在端口 8889 上启动它。但同样的错误消息。

如果我可以提供有关该问题的更多信息，请告诉我。
