刚刚将 Ubuntu 更新到 22.04，现在我无法打开 Jupyter Notebook

Question

当我尝试启动 Jupyter Notebook 时，浏览器启动并出现以下错误：

Access to the file was denied

The file at /home/benjamin/.local/share/jupyter/runtime/nbserver-11758-open.html is not readable.

It may have been removed, moved, or file permissions may be preventing access.

我试过跑步

jupyter lab clean --all
pip3 install jupyterlab --force-reinstall

根据这里的建议：Jupyter Notebook: Access to the file was denied。命令运行，但我仍然收到“访问文件被拒绝”错误。此外，在重新安装命令它吐出这个：

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
spyder 4.2.5 requires pyqt5<5.13, which is not installed.
spyder 4.2.5 requires pyqtwebengine<5.13, which is not installed.
conda-repo-cli 1.0.4 requires pathlib, which is not installed.

fermipy 1.0.1+5.g5a57 requires astropy<4, but you have astropy 4.2.1 which is incompatible.

这可能是也可能不是问题的一部分。

Answer 1

你尝试设置了吗

c.NotebookApp.use_redirect_file = False

在 jupyter_notebook_configuration.py 文件中？

如果您尝试过，您是否删除了行首的“#”？

我在 Ubuntu 22.04 上遇到了同样的问题，这解决了它。

Answer 2

更新：我现在可以使用打印到控制台的 URL 访问笔记本。 （复制粘贴到火狐浏览器即可）

我仍然想弄清楚如何使用“jupyter notebook”命令打开它，就像它在更新之前的工作方式一样，但现在这是一个有用的解决方法。

Answer 3

我首先创建了文件： jupyter notebook --generate-config 然后我取消注释并按照您所说的更改 c.NotebookApp.use_redirect_file 行

现在它可以工作了！
