anaconda新建python3创建代码失败,Jupyter:创建笔记本失败,加载笔记本时出错
首先,应用程序似乎“不受信任”,在提示时单击“信任”将无法执行任何操作:
其次,尝试创建新的Jupyter笔记本时出现以下错误:
Creating Notebook Failed:
The error was: Unexpected error while saving file: Desktop/Complete-Python-3-Bootcamp-master/03-Methods and Functions/Untitled.ipynb database is locked
第三,如果我尝试加载其他Jupyter笔记本,我会遇到问题。例如,尝试打开03函数练习练习.ipynb来自Jupyter的“Python训练营”
我得到以下信息:
Error loading notebook
An unknown error occurred while loading this notebook. This version can load notebook formats or earlier. See the server log for details.

这是最近才开始的,我不知道为什么。似乎这两个错误(无法创建新笔记本和无法打开现有笔记本)都是由某种权限问题引起的。我不应该从上面的图片列表中的一些笔记本文件可以打开没有问题。感谢您的帮助!
