Error: Specifier not found in cache

[durraniu]

Thanks for creating this demo. I am on Windows 10. I cloned your repo and tried rendering the index.qmd and R-shinylive-demo.qmd files after installing the shinylive package. But I get the following output with an error. Could you help me finding out what's wrong?

I can't reproduce this on my end with material posted as-is in the repository.

I would suggest making sure that you are:

1. up-to-date with the version of R present
   • This should be R 4.4.1 or R 4.4.2
2. using the R shinylive package on CRAN.

install.packages("shinylive")

3. Running Quarto v1.5.57
   • Note: if you have an outdated copy of RStudio, this may be problematic.

In the Terminal tab within RStudio, type:

quarto check

You should get:

Quarto 1.5.57

      Pandoc version 3.2.0: OK

My R version is 4.3.2 so that may be the culprit. The remaining requirements are okay, i.e., shinylive is installed and quarto version is 1.6.32.
Thank you for the help. I am closing the issue.

[coatless]

@durraniu there's a lot of instability in the latest preview release of Quarto (v1.6.32)

quarto-dev/quarto-cli#10951

I would suggest downgrading. The error is suggesting a deno issue, which might have crept back in.

[durraniu]

Thanks for pointing that out. I'll try upgrading R and downgrading quarto and report back.

[durraniu]

Update: With R 4.4.2 and Quarto 1.5.57, the app works! Thank you.

[coatless]

@durraniu great to hear. FYI, this is a known issue with Quarto v1.6 pre-release due to a change in how deno imports need to occur. Details: https://prerelease.quarto.org/docs/projects/scripts.html#deno-scripts

The issue is already being tracked at the appropriate repository:

quarto-ext/shinylive#65
posit-dev/shinylive#185

The only downside is if you need to use {quarto-shinylive} extension, you can't use it with a pre-release!
