启动 Kernel 失败。 操作系统错误：[WinError 123]

Question

几天以来，我无法在 python 交互式 window 中运行我的代码（甚至不是简单的print("Hello wolrd") ) 文件）。 当我尝试启动 kernel 时，我收到以下消息：

启动 Kernel 失败。 OSError: [WinError 123] Die Syntax für den Dateinamen, Verzeichnisnamen oder die Datenträgerbezeichnung ist falsch: '"c:'。查看 Jupyter 日志以获取更多详细信息。

我正在使用 python 3.6.13 并从我使用 anaconda 管理的虚拟环境运行。 我已经安装了 ipykernel。 当我对我的其他 python 版本 3.9.7 执行相同操作时，它工作得很好。

我已经在这里浏览了一堆线程，但找不到解决方案。

我正在开发 Windows 11 Pro，64 位系统。

我在这里上传了 jupyter 日志的完整 output 并在下面的这篇文章中添加了尽可能多的内容。

感谢您的帮助！

Answer 1

最近，jupyter 正在修复.env相关问题。

您可以尝试安装vscode 内部人员并安装jupyter扩展的预发布版本。

Answer 2

它发生在我身上，我尝试通过pip uninstall ipykernel ，打开vscode，然后在运行笔记本文件时通过vscode中的弹出窗口安装ipykernel，它再次工作

Answer 3

有同样的错误，非常沮丧不能在 VSCode Jupyter Notebook 中使用 arcpy。 上面的解决方案成功了：确保选择了 arcgispro-py3-clone 环境：

pip uninstall ipykernel 
python -m pip install ipykernel
