问题:
Jupyter 无法保存和创建（我想象中的删除）任何文件类型。但我可以正常加载它们。
创建文件的示例
创建文件失败，创建新文件时出现错误。
'''在保存文件 'untitled.txt' 时发生意外错误：[Errno 2] 没有这样的文件或目录： 'C：\ Users \ me \ Documents \ jupyter_notebooks \ untitled.txt' '''
保存文件的示例

尝试过：问题仍然存在。
我仔细检查了文件夹位置，它匹配。
C:\Users\me\Documents\jupyter_notebooks
我还尝试了：安装和运行，可以打开和读取，但不允许进行任何更改。
pip3 install --upgrade --force-reinstall --no-cache-dir jupyter

系统:
- Windows 10
- Python环境: 2.7 & 3.5
- 包管理器: pip / pip3
可能的贡献因素: 两天前做了一些系统更改，从那时起问题就出现了。我认为这是一个权限问题。我记得取消了一个"执行脚本的权限复选框"，但它似乎只影响了Jupyter。
不可接受的解决方案:
"尝试使用Anaconda"，"重新安装Windows" - 系统运行良好，除了Jupyter无法进行更改。
提前感谢您的帮助。
