jupyter笔记本计算机错误权限被拒绝：IPYNB未定义

Question

当我在命令提示符下键入jupyter notebook时，我在网络浏览器中将其获取，但是当我打开python-3笔记本时，其显示错误

Dialoq框随附以下内容

Creating Notebook Failed
An error occurred while creating a new notebook.
Permission denied: Untitled ipynb

screenshot of the error

这是propmt命令中的内容

[I 15:17:21.898 NotebookApp] Creating new notebook in

昨天我也通过生成conifg更改了deafault jupyter笔记本浏览器并将其更改为chrome，但这不是问题吗？请给出详细说明？ 我也听说它与目录名称有关，如果是这种情况，请告诉我如何更改它 谢谢
