python - pywintypes.error : (50, 'GetFileSecurity' , 'The request is not supported.' ) 在网络驱动器上使用 Jupyter Notebook

Question

我目前正在尝试在网络驱动器上使用 miniconda + jupyter(与 pip 一起安装)的组合，但出现以下错误:

pywintypes.error: (50, 'GetFileSecurity', 'The request is not supported.')

我目前在一家公司工作，因此我们正在处理有关访问权限的一些限制。不幸的是，我只能在网络驱动器上尝试 jupyter，更改本地硬盘驱动器需要我没有的管理员权限。

完整的错误输出:

对此类错误有任何想法或经验吗？

Answer 1

对于遇到此问题的任何人，这似乎是由于更新了 jupyter notebook 或任何其他可以更新它的软件包。

解决问题的步骤如下，

pip 安装 jupyter
pip 安装 jupyter-client==5.3.1
python -m ipykernel 安装 --user
