python - Jupyter Notebook、Windows 10 中的内核错误(Errno 13 权限被拒绝)

Question

我已经在 Windows 10 上安装了 Jupyter Notebook。我可以执行 jupyter notebook 命令。它打开并显示当前路径目录的列表。我还可以创建或打开笔记本。但是当我这样做时，右上角出现内核错误。点击后出现这个窗口:

Failed to start the kernel

Unhandled error

我文件中的代码没有以不同的颜色突出显示，当我运行它时没有任何反应。

我是编程新手，所以请尽量用简单的语言给出建议，详细描述每个步骤。

过去，我尝试过删除 Python，安装不同版本的 Python，安装 Anaconda。此外，为了使用 tensorflow，我创建了一个特殊的环境。但是这个错误保持不变。我怀疑问题是路径中的双反斜杠(“//”)，但我完全不知道如何解决这个问题。但也许问题出在其他地方。

同样的问题在这里。对我有用的是以管理员身份运行 Anaconda Navigator。希望它也对你有用。
