jupyter nbconvert --to slides 由于访问权限而失败

Question

我正在尝试使用 nbconvert 为我的笔记本生成幻灯片。使用 windows、jupyter 和 python 3.

https://nbconvert.readthedocs.io/en/latest/usage.html#convert-revealjs

我是运行管理员模式下命令shell中的命令：

jupyter nbconvert C:\files\notebook.ipynb --to slides --post serve

files\ 目录包含一个名为 reveal.js 的目录。

出现以下错误，

[NbConvertApp] Converting notebook C:\files\notebook.ipynb to slides
[NbConvertApp] Writing 379320 bytes to C:\files\notebook.slides.html
[NbConvertApp] Serving local reveal.js

OSError: [WinError 10013] An attempt was made to access a socket in a way forbidden by its access permissions

这表明该端口已在本地使用 - 我相信它默认为 8000。有没有办法在运行 nbcovert 命令时指定端口？例如。不是 8000。

NB 正在创建文件 notebook.slides.html，我可以在不同的端口上用 http.server 手动提供它。

您确实可以更改端口。修改命令如下：

jupyter nbconvert C:\files\notebook.ipynb --to slides --ServePostProcessor.port=8910 --post serve

jupyter nbconvert --to slides 由于访问权限而失败

jupyter nbconvert --to slides fails due to access permissions

python-3.x

jupyter-notebook

nbconvert
