刚将Ubuntu更新为22.04，现在我可以打开Jupyter笔记本

Question

当我尝试启动jupyter笔记本时，浏览器会启动，我会收到以下错误：

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.

我尝试

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

按照此处的建议进行运行： jupyter笔记本：对文件的访问被拒绝。命令运行，但我仍然可以拒绝对文件的访问。另外，在重新安装命令上，它会吐出：

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.

它可能是问题的一部分。

Answer 1

您是否尝试

c.NotebookApp.use_redirect_file = False

在jupyter_notebook_configuration.py文件中设置？

如果您尝试过，您是否在行开始时删除了“＃”？

我对Ubuntu 22.04遇到了同样的问题，并将其修复了。

Answer 2

更新：我现在可以使用打印到控制台的URL立即访问笔记本。 （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”打开它。 。

Answer 3

我首先用：
jupyter笔记本 - 生成型
然后，我没有服从并更改行C.NoteBookApp.use_redirect_file，如您所说

，现在可以使用！

Answer 4

我使用Ubuntu上的Snap的Firefox面临同一问题。22.04。
我注意到设置 c.notebookApp.use_redirect_file = false 在生成 jupyter_notebook_config.py.py 在启动 jupyter笔记本时起作用，但失败了 jupyter -lab （粘贴错误）。我发现做类似的操作以解决 jupyter-lab ：

jupyter server --generate-config

然后编辑生成的 ./ jupyter/jupyter/jupyter_server_server_config.py.py 和set c.serverapp.use_redirect_file_file_file_file = false 。现在运行 jupter-lab 也可以在snap firefox中工作。也许您可以这样尝试，并且只需通过 Jupyter-lab 运行，如果它也适合您。

顺便提一句。如果您只使用Chrome，则无需这些问题，以某种方式仅出现Ubuntu上的Snap 22.04的Firefox出现问题。
否则，您可以查看 jupyter笔记本 - debug 和/或重新安装jupyterlab。

Answer 5

我使用Epiphany Web浏览器，而不是Firefox作为默认的Web浏览器，每个浏览器都可以正常工作

Answer 6

我发现的问题是，发射器没有使用可行的jupyter笔记本的路径。从终端i获得：

$ 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/bin/bin/jupyter-notebook 不会。如果您在 .local/share/applications/jupyter -notebook.desktop 的Exec行中使用第一个。

[Desktop Entry]
Name=Jupyter Notebook
Comment=Run Jupyter Notebook
