Question

我正在尝试以root用户身份在Jupyter笔记本中运行pyspark。我通过编辑/root/.jupyter/jupyter_notebook_config.py为笔记本启用了root访问权限。我还编辑了https://blog.sicara.com/get-started-pyspark-jupyter-guide-tutorial-ae2fe84f594f下方法1-配置PySpark驱动程序一节中提到的bashrc文件。但是在尝试以root身份运行pyspark时我得到

xdg-open：没有方法可用于打开“ file：///root/.local/share/jupyter/runtime/nbserver-20051-open.html”

升级系统后，我遇到了类似的问题。该错误表明不应以root模式打开Firefox，但是如果不使用sudo，则jupyter notebook会引发权限被拒绝错误。我通过递归更改以下内容的权限来解决了这个问题-尽管我自己对该解决方案并不满意-

~/.local/share/jupyter/runtime/*

基本上，我更改了.local的权限，然后更改了./local/share，依此类推，一直到运行时的内容。然后，当我在终端中运行jupyter notebook（注意，这里没有sudo）时，它就起作用了。

不过，还有另一种解决方案。如终端窗口所示，您可以手动将指定的URL复制并粘贴到首选浏览器中。但这每次都必须手动完成。

P.S。我的系统是运行Ubuntu 18.04的个人笔记本电脑。
