未找到 Web 浏览器：找不到可运行的浏览器。Jupyter-笔记本

Question

Jupyter-notebook 不会打开网络浏览器。之前它运行良好，然后在 Windows 10 提示更新后，它开始在 Microsoft Edge 中打开。当我尝试将其更改为默认浏览器（即 chrome）时，它根本无法打开。

我按照如何在 Windows上的chrome 中打开 Jupyter notebook尝试将其更改回 chrome。

当我尝试运行时

jupyter notebook

在 cmd 中我得到的是

[I 21:39:08.015 NotebookApp] JupyterLab extension loaded from C:\Users\roy\Anaconda3\lib\site-packages\jupyterlab
[I 21:39:08.015 NotebookApp] JupyterLab application directory is C:\Users\roy\Anaconda3\share\jupyter\lab
[I 21:39:08.015 NotebookApp] Serving notebooks from local directory: C:\Users\roy
[I 21:39:08.015 NotebookApp] The Jupyter Notebook is running at:
[I 21:39:08.015 NotebookApp] http://localhost:8888/?token=d0a958999d7e59da3f097809882e8f40eb5845e3a07cebe8
[I 21:39:08.031 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
[W 21:39:08.109 NotebookApp] No web browser found: could not locate runnable browser.

    To access the notebook, open this file in a browser:
        file:///C:/Users/roy/AppData/Roaming/jupyter/runtime/nbserver-1516-open.html
    Or copy and paste one of these URLs:
        http://localhost:8888/?token=d0a958999d7e59da3f097809882e8f40eb5845e3a07cebe8

但是，当我将 url 复制并粘贴到 Web 浏览器中时，它工作正常。

解决了。

我去了我的用户目录中的 .jupyter 文件夹 > 打开了 jupyter_notebook_config.py 文件 > 然后从 c.NotebookApp.browser = 'C:\Program Files (x86)\Google\Chrome\Application\chrome.exe '编辑了这一行到 c.NotebookApp.browser = u'C:/Program Files (x86)/Google/Chrome/Application/chrome.exe %s'

现在它运作良好。
