Jupyter 在 Debian 上出现 404 错误，我无法打开任何笔记本

Question

我目前无法在运行 Debian 12 的戴尔笔记本电脑上使用 jupyter。我正在 python virtualenv 中运行 jupyter lab。

当我运行

jupyter lab

时，我首先收到以下反复出现的错误消息：

[W 2025-01-15 18:44:52.720 ServerApp] 404 GET /api/collaboration/room/JupyterLab:globalAwareness ([email protected]) 39.53ms referer=None

jupyter 菜单在我的 Firefox 浏览器中显示得很好。

然后，当我尝试创建新笔记本时，出现以下 404 错误：

[W 2025-01-15 18:45:03.095 ServerApp] 404 PUT /api/collaboration/session/Untitled.ipynb?1736963103090 ([email protected]) 1.33ms referer=http://localhost:8888/lab

打开的笔记本无法加载：

这是一些控制台输出：

Jupyter 版本：

当我在 virtualenv 之外运行

jupyter-notebook

时，我遇到了同样的错误，并且我仍然无法运行任何笔记本。

我不认为它来自 jupyter 安装，因为我在多次安装中得到了相同的结果。我还能够在 docker 容器中运行 jupyterlab。

我升级系统后也遇到同样的问题。

就我而言，解决方案是删除 Jupyter 存储在整个系统多个位置的配置和数据。

首先，检查 Jupyter 可能使用哪些路径：

$> venv/bin/jupyter --paths
config:
    ./venv/etc/jupyter
    /home/<USER>/.jupyter
    /usr/local/etc/jupyter
    /etc/jupyter
data:
    ./venv/share/jupyter
    /home/<USER>/.local/share/jupyter
    /usr/local/share/jupyter
    /usr/share/jupyter
runtime:
    /home/<USER>/.local/share/jupyter/runtime

其中一些路径可能不存在，因此您不需要处理它们。其他人可能拥有您打算使用的实际配置和数据（在我的例子中，这是位于

./venv/

的虚拟环境）。

接下来，（重新）移动那些可能包含过时信息的目录，例如，

mv /home/<USER>/.jupyter /home/<USER>/.jupyter.bck # keep as a backup
sudo mv /usr/share/jupyter /usr/share/jupyter.bck

移动配置目录解决了我遇到的一些奇怪但无害的警告。移动数据目录解决了 404 问题并允许我再次打开我的笔记本。

请告诉我这种方法是否适合您；我们可以稍后更新此答案以供以后参考。
