在终端中打开 Jupyter-Notebook 即可打开 Telegram 桌面！

我在使用 Ubuntu 20.04.2 LTS。

当我想在终端中打开 Jupyter-Notebook 时，电报桌面应用程序就会打开。

Jupyter-Notebook 实际上是在后台打开的。所以我可以打开浏览器并使用它。

输出如下：

(geospatial) siavash@siavash-fra:~$ jupyter-notebook 
[I 16:59:52.522 NotebookApp] Serving notebooks from local directory: /home/siavash
[I 16:59:52.522 NotebookApp] The Jupyter Notebook is running at:

    To access the notebook, open this file in a browser:

    Or copy and paste one of these URLs:

我也看了这类似的问题，但它没有回答我的问题。

答案1

我发现了问题：安装 telegram 后，奇怪的是它使 telegram 成为打开 HTML 文件的默认应用程序。这就是为什么jupyter-notebook在终端中运行后，它会尝试使用 telegram 打开链接。

因此，要解决这个问题，只需找到任何 HTML 文件。右键单击它。转到Properties。在Open With选项卡中选择您的浏览器，然后单击Set as default。

问题已解决。下次电报将无法打开。相反，您将在浏览器上运行 jupyter-notebook。

答案2

值得注意的是，你应该通过不同的端口。

我无法重现此错误，也无法找到强制 telegram-desktop 使用其他端口的方法，但您可以将 jupyter notebook 配置为使用除 之外的端口8888。

首先，检查文件是否/home/USERNAME/.jupyter/jupyter_notebook_config.py存在。如果不存在，则运行jupyter notebook --generate-config。

然后，打开此文件并取消注释以下行，将端口更改为8889，例如：

c.NotebookApp.port = 8888
                      ^ Change this port to 8889

保存文件并再次运行 jupyter notebook。从现在起，电报桌面应该不会打开。
