Installing Extensions in RStudio

[axiomtutor]

Description

I'm trying to install extensions for Quarto presentations (for example, the illinois-revealjs extension) inside of RStudio. My computer runs Windows 11.

I tried using the documentation https://quarto.org/docs/extensions/managing.html

and https://quarto.org/docs/extensions/revealjs.html

and also following the instructions from the extension's GitHub. https://github.com/coatless-quarto/illinois-revealjs

I also tried looking for any info on RStudio and its GitHub page but struck out there -- I think someone over there actually asked the same question a while ago and got no responses.

---

After trying all of the above, I think it successfully downloaded the extension, but when I try to run

---
title: "title"
author: "me"
format: 
  illinois-revealjs:
    chalkboard: true
editor: visual
---

## TEST

I get the error message

ERROR: Unable to read the extension 'illinois'.
Please ensure that you provided the correct id and that the extension is installed.

    at loadExtension (file:///C:/Users/username/AppData/Local/Programs/Quarto/bin/quarto.js:42097:15)
    ...

and the ... just covers up a bunch of other very similar lines.

However, when I set illinois-revealjs to just revealjs then it renders.

Anyone have guidance on how to do the installation / use inside of RStudio? Thanks! :)

If the extension installed in the same folder than your document, or at the root of the Quarto project ?

Can you check this ?

You can run in your working directory / quarto project or document folder the following

quarto list extensions

It should find the extension.

If not installed in the right place, quarto won't find it.

Hi, thanks for the help!

When I run quarto list extensions it does print the extension. So it seems like it's installed.

However, when I run $ quarto update coatless/quarto-illinois or $ quarto add coatless/quarto-illinois it responds with the error

Quarto extensions may execute code when documents are rendered. If you do not
trust the authors of the extension, we recommend that you do not install or
use the extension.

and so on with more lines of the error message. I used the instructions here: https://github.com/coatless-quarto/illinois-revealjs

and so I ran quarto use template coatless/quarto-illinois. This caused no error messages, but it also does not fix any of the previous errors. It also does not create an example .qmd file as the README says.

I believe this is just an issue because the repo was renamed, but not the instruction in the README.

Try

quarto add coatless-quarto/illinois-revealjs

[cderv]

I opened an issue so that we try to handle such case with more helpful error

Thanks for the report !
