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，我得到以下错误:

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.

我试着运行

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

按照这里的建议:Jupyter Notebook:访问文件被拒绝。命令运行了，但我仍然得到访问文件被拒绝的错误。同样，在重新安装命令中，它会输出如下内容:

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.

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

这可能是问题的一部分，也可能不是。

Answer 1

你试过设置

c.NotebookApp.use_redirect_file = False

在jupyter_notebook_configuration.py文件中?

如果您尝试了，您是否删除了行首的"#"?

我在Ubuntu 22.04中也遇到了同样的问题，这个修复了它。

Answer 2

更新:我现在能够通过使用打印到控制台的URL访问笔记本。(只需复制并粘贴到Firefox浏览器中)

我还是想弄清楚如何只用"jupyter notebook"打开它;命令它在更新之前的工作方式，但现在这是一个有用的解决方案。

Answer 3

我首先用:Jupyter notebook——generate-config然后取消注释并更改c.NotebookApp行。Use_redirect_file

，现在它工作了!

Answer 4

我在Ubuntu 22.04上使用snap的Firefox时遇到了同样的问题。我注意到，在启动jupyter notebook时，在生成的jupyter_notebook_config.py中设置c.NotebookApp.use_redirect_file = False有效，但jupyter-lab失败(您粘贴的错误)。我发现做一些类似的事情来解决jupyter-lab的问题:

jupyter server --generate-config

编辑生成的./jupyter/jupyter_server_config.py，设置c.ServerApp.use_redirect_file = False。现在运行jupter-lab也适用于snap firefox。也许你可以尝试这种方式，只是通过jupyter-lab运行，如果它也适用于你。

顺便说一句。如果你只使用Chrome，这些都不需要，不知何故，这个问题只出现在Ubuntu 22.04上的firefox上。否则，你可以检查jupyter notebook --debug和/或重新安装JupyterLab。

Answer 5

我使用epiphany浏览器而不是Firefox作为默认浏览器，一切都很好

Answer 6

我发现的问题是启动器没有使用通往Jupyter Notebook的有效路径。从终端我得到:

$ whereis jupyter-notebook
jupyter-notebook: /home/brombo/miniconda3/bin/jupyter-notebook /home/brombo/.local/bin/jupyter-notebook

命令/home/brombo/miniconda3/bin/jupyter-notebook将启动笔记本，但/home/brombo/.local/bin/jupyter-notebook不会。如果你在.local/share/applications/jupyter-notebook.desktop的exec行中使用第一个，一切都可以工作-

[Desktop Entry]
Name=Jupyter Notebook
Comment=Run Jupyter Notebook
Exec=/home/brombo/miniconda3/bin/jupyter-notebook %f
Terminal=true
Type=Application
Icon=notebook
StartupNotify=true
