在 VS Code 中调试 Jupyter Notebook 的问题：“需要 ipykernel 安装程序”和 Print 语句失败
Debugging Issue with Jupyter Notebooks in VS Code: 'ipykernel setup required' and Print Statement Failures
问：
尝试在 Visual Studio Code 中调试 Jupyter 笔记本时遇到问题。我有一个带有多个交互式小部件的单元格，使用 ipywidgets。当我开始调试时，我收到以下错误和警告：
[error] Failed to handle iopub message as a result of some comm message {
...
} Error: Cannot call start again
[warn] Cell completed with errors undefined
我可以很好地运行笔记本中的所有单元格，并且打印语句在几次执行中按预期工作，或者直到我尝试调试。在我尝试调试后，我收到一个对话框，上面写着“此功能需要 ipykernel 设置”，print 语句不再显示，并且类似命令也不产生任何输出。conda info
我尝试了以下步骤：
- 更新、卸载和重新安装 ipykernel、Jupyter、Miniconda3 和 Python 扩展
- 更新、卸载和重新安装 VS Code
- 重新加载 VS Code 窗口
- 完成 VS Code 和 Python 的卸载和重新安装，包括删除我的主目录中的相关文件夹、appdata 和程序文件。
这些步骤均未解决问题。很多时候，重新启动内核或重新加载窗口会暂时修复它，但现在调试无论如何都不起作用。 我认为问题与我的路径变量的配置方式有关，它们不允许 Miniconda3 与 VS Code 和 Jupyter 一起使用。
- Miniconda3 安装路径：
C:\Users\User\AppData\Local\miniconda3 - VS Code 中的 Python 解释器路径：
C:\Users\User\Desktop\Folder\.conda\python.exe - PATH 环境变量：
C:\Users\User\AppData\Local\miniconda3;
C:\Users\User\AppData\Local\miniconda3\Library\mingw-w64\bin;
C:\Users\User\AppData\Local\miniconda3\Library\usr\bin;
C:\Users\User\AppData\Local\miniconda3\Library\bin;
C:\Users\User\AppData\Local\miniconda3\Scripts;
C:\Users\User\AppData\Local\miniconda3\bin;
C:\Users\User\AppData\Local\miniconda3\condabin;
- Conda 环境：

此功能需要 ipykernel 设置
这意味着 ipykernel 包未安装在当前的 jupyter 内核中。
您可以单击右上角的按钮来更改当前的 jupyter 内核。
另一种方法是在当前环境中安装 ipykernel 软件包。

我安装了ipykernel。我已经卸载、重新安装和更新了几次。我将其列在 的输出中。在尝试调试之前，我也可以使用 ipykernel 的功能，但在调试后，ipykernel 停止工作。conda list
