WinError笔记本内核错误- FileNotFoundError：[ Jupityr 2]

我最近在Anaconda上遇到了一些库的问题，所以我重新安装了Anaconda，当我再次启动它时，Jupityr Notebook内核错误发现了以下文本：

FileNotFoundError: [WinError 2] The system cannot find the file specified当我启动并打开一个文件时，我得到了这个错误。它拒绝运行代码，只是坐在那里有点死气沉沉。内核错误出现在几乎所有使用Jupyter笔记本打开的文件中。

下面的解决方案对我很有效。您可以在虚拟环境中的命令提示符或Anaconda提示符中运行此代码。
python -m ipykernel install --user有关详细的解释和说明，请查看
给你。

此解决方案可能对Windows用户有帮助。
转到
(AppData是隐藏文件)并删除名为的文件夹
和
(如果存在。)
删除
..。
pip安装jupyter
我使用的jupyter没有anaconda，这完美地解决了这个问题。不确定这是否适用于jupyter和anaconda。
