Unable to render quarto doc with embedded shinylive

[ryjohnson09]

Currently running quarto version 1.2.157, shinylive version 0.0.7.

After following the directions on https://github.com/quarto-ext/shinylive, when I try to render the quarto doc, I get the following error:

Error: Option '--sw-dir' requires an argument.

I've tried to figure out what the --sw-dir is, but not having any luck. Let me know if you need any more information!

I suspect that is happening because param("project-offset") is returning an empty string here:

https://github.com/quarto-ext/shinylive/blob/d69d4d94777d486579ad10f7cd88a726a1747a02/_extensions/quarto-ext/shinylive/shinylive.lua#L34-L39

@ryjohnson09 Can you try the following:

quarto install extension quarto-ext/shinylive@debug-projectoffset
quarto render

As it renders the site, it should print out something like:

projectOffset: '.'

What does it print when you run it?

[ryjohnson09]

Did the install step, and then ran quarto render and got the following output:

❯ quarto render
ERROR: The specified directory ('.') is not a Quarto project

Looks like I didn't set up a Quarto project 🤦‍♂️

quarto create-project .
quarto preview /Users/ryanjohnson/Desktop/Shiny_for_Python/Shiny4Python.qmd --to html --no-browser --no-watch-inputs

Works like a charm - thanks @wch 🎉

Easy mistake to make! I'll have it print out a more helpful error message when this happens.
