How did you install Quarto? If you installed it using root access, then root access might be needed here as well.

This being said, I don't think you can upgrade Typst embedded version, as you can't for Pandoc.
Typst/Pandoc are updated and embedded at each new version of Quarto.
quarto typst is there to use the embedded version of Typst and nothing more.
Here, I am almost certain, there is no bug, but I'll let one of the main developers confirm this.

[ForceBru]

@mcanouil, I installed Quarto with the regular installer. Indeed, ls -lah /Applications/quarto/ shows that everything in this directory is owned by root.

I was able to update using sudo:

/A/quarto> sudo quarto typst update
Password:
Downloading release ...
 10.0 MiB /  10.0 MiB (100 %)  10.0 MiB/s in  0s ETA:  0s
/A/quarto> quarto typst --version
typst 0.11.0 (2bf9f95d)

Needless to say, neither Pandoc nor Quarto directly supports Typst 0.11, so this may or may not work.

We hope to look into it soon!

I agree with that. I did no know typst allowed to be updated from itself. Doing this will probably break Typst support with Quarto and Pandoc as you mention @gordonwoodhull.

I don't think quarto typst update should be allowed to prevent any breaking of the Quarto installation

[cscheid]

Agreed with both @cderv and @gordonwoodhull on this being a bad idea that we should try and disallow. I'm going to rename this issue accordingly.

[baptiste]

Is there any way to point Quarto to use the system Typst instead of the built-in one? I'm trying to use contexts in Typst, which is new.

Our plan is to release Quarto 1.5 with support for Typst 0.11. We're in the process of ensuring everything works.

In the meantime, you can use the QUARTO_TYPST env variable, but that Voids The Warranty.

In other words: we make no promise if something breaks when you run Quarto with a non-builtin version of Pandoc or Typst!

I just made a PR adding some documentation for this hidden feature, since it is extremely useful and I only found it in this discussion thread.

Really excellent & helpful feature; thanks.
