python - Jupyter 无法在主目录之外启动

Question

我全新安装了 Anaconda 3.7，并尝试通过执行以下操作打开 Jupyter 笔记本:

1. 已卸载 Anaconda 3.6。
2. 删除了注册表中的所有 anaconda、jupyter 和 python 项。
3. 删除了文件系统上的所有 anaconda、jupyter 和 python 文件和文件夹。
4. 已重新启动。
5. 已安装 Anaconda 3.7 64 位(在 Windows 10 Pro 64 位上)。我在安装程序中勾选了“添加到路径”选项。
6. 打开 PowerShell。
7. 使用 jupyternotebook 命令启动 jupyternotebook。
8. 尝试在浏览器中选择笔记本来打开它。

我收到以下错误:

使用 conda update --all 更新软件包没有什么区别。

使用 jupyter lab 会出现相同的错误。

有谁知道为什么会发生这种情况以及如何解决它？

我提交了bug with the Jupyter project .

Answer 1

尝试一次: 1. 打开 Anaconda 提示符2. 转到 C:\Users\your_name3.编写jupyter trust untitled.ipynb4.然后，编写jupyter笔记本
