我试图以root用户的身份在Jupyter笔记本上运行pyspark。我通过编辑 root.jupyterjupyter_notebook_config.py 启用了笔记本的 root 访问。我还编辑了在 https:/blog.sicara.comget-started-pyspark-jupyter-guid-tutorial-ae2fe84f594f。 方法1 - 配置PySpark驱动。然而，当我试图以root身份运行pyspark时，我得到的结果是
xdg-open: 没有打开'file:/root.localsharejupyterruntimenbserver-20051-open.html'的方法。

在我升级系统后，我也遇到了类似的问题。sudo 不使用，那么 jupyter notebook 抛出 不准 错误。我解决了这个问题--虽然我自己对这个解决方案不是很满意--通过递归地改变下面的权限。
~/.local/share/jupyter/runtime/*
所以基本上，我改变了以下文件的权限 .local那么 ./local/share等，一直到运行时的内容。然后，当我运行 jupyter notebook (注，不 sudo 这里）在终端，它的工作。
不过，还有一种解决办法。正如终端窗口所说，你可以手动复制并粘贴指定的URL到你喜欢的浏览器中。但每次都要手动完成。
P.S.我的系统是一台运行Ubuntu 18.04的个人笔记本。
