Ipython Notebook仅以root身份运行

Question

我试图在iPython中导入一个笔记本(更新后的Jupyter).但由于某种原因,我只能以root用户身份运行才能导入任何笔记本.否则,我收到所有笔记本的以下错误.

加载此笔记本时发生未知错误.此版本可以加载v4或更早版本的笔记本电脑.有关详细信息,请参阅服

iPython3笔记本能够加载笔记本电脑.我有什么办法可以解决这个问题吗？

答: KT.的解决方案有效.我认为我第一次以root身份运行Jupyter,导致KT提到的非root用户无法访问这些文件.

Answer 1

好吧，让我在这里猜测一下。

当你ipython notebook第一次跑步时，它在下面root。因此，Jupyter 使用的一些文件从一开始就被创建为 root 拥有的文件。现在，每当您以非 root 用户身份运行 Jupyter 时，他都会无法写入这些文件，从而导致您看到的错误，这并不奇怪。

在您在日志中看到的特定情况下，Jupyter 在写入nbsignatures.dbSQLite 数据库时出现问题。该文件应位于 Jupyter 中DATA_DIR，通常类似于~/.local/share/jupyter.

如果您没有此目录，您可以通过运行ipython并执行以下操作来找到它，例如：

In [1]: from jupyter_core.application import JupyterApp
In [2]: JupyterApp().data_dir
Out[2]: u'/home/ubuntu/.local/share/jupyter'

您现在需要做的是确保该目录中的所有内容都归正确的用户所有，而不是 root 用户。这可能意味着做类似的事情

# chown -R <yourusername>.<yourusername> ~/.local/share/jupyter

作为根。
