使用命令行升级 pip，现在 Jupyter 笔记本不工作

Question

因此，我决定使用命令行按照 web 页面上的一些说明使用命令行升级 pip，现在当我尝试打开 Jupyter 笔记本时，我只得到一个空白页面，并显示一条小消息：“此页面应将您重定向到 Jupyter Notebook。如果没有，点击这里到 go 到 Jupyter。”，同时命令行显示如下：

    C:\Users\Propietario>jupyter notebook
[I 16:28:26.158 NotebookApp] Serving notebooks from local directory: C:\Users\Propietario
[I 16:28:26.158 NotebookApp] Jupyter Notebook 6.3.0 is running at:
[I 16:28:26.158 NotebookApp] http://localhost:8888/?token=767d91ee67804085a541023b7f49efa33d0a3cddb17be4c6
[I 16:28:26.158 NotebookApp]  or http://127.0.0.1:8888/?token=767d91ee67804085a541023b7f49efa33d0a3cddb17be4c6
[I 16:28:26.159 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
[C 16:28:26.205 NotebookApp]

To access the notebook, open this file in a browser:
    file:///C:/Users/Propietario/AppData/Roaming/jupyter/runtime/nbserver-8488-open.html
Or copy and paste one of these URLs:
    http://localhost:8888/?token=767d91ee67804085a541023b7f49efa33d0a3cddb17be4c6
 or http://127.0.0.1:8888/?token=767d91ee67804085a541023b7f49efa33d0a3cddb17be4c6
C:\Users\Propietario>jupyter notebook

我不确定它是否是我升级 pip 或类似的路径。

刚刚检查了版本：

C:\Python\Python39\Scripts>pip --version
pip 21.0.1 from c:\python\python39\lib\site-packages\pip (python 3.9)

我会感谢一些帮助。 谢谢

Answer 1

jupyter notebook stop 8888

如果这不起作用

sudo pkill -1 -f python
