Download PDF - nbconvert failed: Unsupported platform: freebsd12

[ManPython]

What is reason that jupyter is Unsupported platform: freebsd12 when want download PDF? ;/

[ivanov]

@ManPython sorry this never got answered: how did you get that message? I suspect this had to do with just not having pandoc installed, but I'm not certain. I'm going through old issues and it seems to me that it makes sense to close this one, let's open a new issue if this is still a problem, and include information about how you installed jupyter (ports? pip? conda?) as well as what versions are being used.

Thanks and happy hacking!

@ManPython thanks for the update - can you post the results of running jupyter troubleshoot in your shell?

Also, how did you install Jupyter tools. I tried to quickly scan https://github.com/jupyter/nbconvert/ but didn't see any similar messages.

webpdf is installed to try generate pdf in this way.. but also failed

When exporting with PDFviaHTML this same error as:

500 : Internal Server Error

The error was:

nbconvert failed: Unsupported platform: freebsd13

[ivanov]

@ManPython I think I tracked this down the webpdf failure to playwright not supporting FreeBSD - see microsoft/playwright#5084 which includes a workaround by adding:

two lines to a global .npmrc to skip browsers install:

playwright_skip_browser_download=1
playwright_browsers_path=/nonexistent

and another possibility here is to export PLAYWRIGHT_BROWSERS_PATH=/nonexistent (which I found via discussion in louislam/uptime-kuma#3642 )

[ManPython]

I see.. many feedback about low support around FreeBSD and Python. Thats poor case, coz this type servers with this OS is very popular coz comfy to prepare for Python and many other tools.
