pywintypes.error: (50, 'GetFileSecurity', 'The request is not supported.') while using Jupyter Notebook on network drive

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

Answer 2

您遇到的问题可能是由于浏览器的访问权限以及 jupyter lab 对运行的访问权限造成的，正如我刚刚痛苦地发现的那样。

我原来的答案可以在这里找到：https://github.com/jupyter/jupyter_client/issues/481

但是对于那些想继续使用最新的 Jupyter lab/Notebook 版本的其他人来说，这是我的故事：

（我运行 Anconda 预装了 Jupyter）：

1- 使用此命令检查环境路径时：jupyter --paths 我得到两个漫游位置，一个用于运行时间和数据！这是因为我使用公司笔记本电脑并且 Windows 设置为将用户数据文件存储在网络上的漫游位置！

(base) C:\>jupyter --paths
config:
    C:\Users\user_x\.jupyter
    C:\ProgramData\Anaconda3\etc\jupyter
    C:\ProgramData\jupyter
data:
    \A-FILEDATA-P\Profile\use_x\AppData\Roaming\jupyter
    C:\ProgramData\Anaconda3\share\jupyter
    C:\ProgramData\jupyter
runtime:
    \A-FILEDATA-P\Profile\use_x\AppData\Roaming\jupyter\runtime

(base) C:\>

2- 所以，我尝试通过添加修改 C:\Users\user_xxx.jupyter\jupyter_notebook_config.py JUPYTER_RUNTIME_DIR = 'C:\Users\user_x\AppData\Roaming\jupyter\runtime' 但它没有用！

2- 但是，这里要注意：我注意到 jupyter lab 命令会触发一个 "stand alone" Chrome 我有一个可移动的 USB 硬盘！在公司 Windows 设置下，它没有任何权限写入笔记本电脑上的其他文件夹位置，因此出现安全错误！

3- 解决方案是在我的 USB 磁盘上设置两个文件夹，其中找到独立 Chrome 并将环境变量设置为指向这些位置，如下所示：

set JUPYTER_RUNTIME_DIR=D:\jupyter\runtime
set JUPYTER_DATA_DIR=D:\jupyter

4- 唯一的问题是您必须在每个新会话开始时执行这两个命令，因为当您重新启动 Jupyter 实验室时它们不会持续存在！正如@Shongololo 指出的那样，您只能从命令行运行其他程序（例如 Spyder）才能读取正确的设置！

如何永久解决这个问题还有待发现。
