Jupyter Notebook 中的 Kernel 错误（Errno 13 Permission denied），Windows 10

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一个笔记本。 但是当我这样做时，我在右上角收到 Kernel 错误。 单击它后，出现此 window：

kernel启动失败

未处理的错误

我文件中的代码没有在不同的 colors 中突出显示，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。

过去我试过删除Python，安装不同版本的Python，安装Anaconda。 此外，为了与 tensorflow 一起工作，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。 但也许问题出在别的地方。

Answer 1

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

Answer 2

自上次更新 jupyter_client 以来出现此问题。 您可以通过降级到最新版本来暂时解决问题。

conda install jupyter_client=5.3.1

Answer 3

以管理员身份运行解决了，太好了！！

Answer 4

我也有同样的问题。 我在 Windows 10/64 位上安装了 Anaconda。 每当我打开 Jupyter Notebook 时，我都会收到 Kernel 错误

并且打开 Spyder，我得到了这个错误

An error ocurred while starting the kernel
The error is:

但是以管理员身份打开工作正常。
