当我尝试启动 Jupyter Notebook 时，浏览器（firefox）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.
我尝试跑步
jupyter lab clean --all
pip3 install jupyterlab --force-reinstall
按照这里的建议：https://stackoverflow.com/questions/70753768/jupyter-notebook-access-to-the-file-was-denied。命令运行了，但我仍然收到“文件访问被拒绝”错误。此外，在重新安装命令中，它输出以下内容：
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.

然后，我尝试强制更新/重新安装消息中提到的软件包（spyder 和 sphinx），然后再次重新安装 jupyter notebook，但仍然收到一条错误消息，内容为：
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed.

我最后尝试的是设置
c.NotebookApp.use_redirect_file = False
并在文件 jupyter_notebook_configuration.py 中取消注释该行，但问题仍然存在，我收到错误“访问文件被拒绝”
我正在使用 Ubuntu 22.04。有人知道如何解决这个问题吗？
Reddit 上也有报道：https://www.reddit.com/r/learnpython/comments/uaipzo/i_just_updated_my_machine_to_ubuntu_2204_now_i/
答案1
更新：我现在可以使用打印到控制台的 URL 访问笔记本。（只需将其复制并粘贴到 Firefox 浏览器中）
我仍然想弄清楚如何仅使用“jupyter notebook”命令打开它，就像更新之前一样，但目前这是一个有用的解决方法。
答案2
我也遇到过同样的问题。真的很痛苦。至少临时解决方案是使用 Chrome 作为默认浏览器。但我真的不明白为什么 Firefox 位于 snap 商店中却无法与 Jupyter 兼容。
