问题：
Jupyter 无法保存、创建（我想删除）任何文件类型。但我可以很好地加载它们
创建文件的例子
创建文件失败 创建新文件时出错。
”’ 保存文件时出现意外错误：untitled.txt [Errno 2] 没有这样的文件或目录：’C:\Users\me\Documents\jupyter_notebooks\untitled.txt’ “’
保存文件的例子

试过： 还是一样的问题
我仔细检查了文件夹位置并且它 匹配
C:\Users\me\Documents\jupyter_notebooks
我也试过： 它安装并运行，能够打开和阅读但不允许更改
pip3 install --upgrade --force-reinstall --no-cache-dir jupyter

视窗 10
Python 环境：2.7 & 3.5
包管理器：pip / pip3
可能的促成因素： 两天前进行了一些系统更改，自问题开始以来。我相信这是一个许可问题。我记得取消选择执行脚本的“权限复选框”。但它似乎只影响 Jupyter
不可接受的解决方案：
“尝试 Anaconda”、“重新安装 windows”——系统运行良好并继续运行，除了 Jupyter 能够进行更改
