What to do when command ```notebook()``` won't prompt a Jupyter installation?

TL;DR: How to make Julia find the jupyter kernel so Quarto can run?

I just installed a new version of Julia (1.8.5) and, given the problems I am dealing with, I assume the packages I had installed didn’t migrate to the new version.

I tried to render a qmd file, but it didn’t work. Then, I went back to the basics and followed the instructions on the Using Julia webpage from the Quarto website..

I reinstalled IJulia, however, when I ran notebook(), I didn’t get prompted with the option to install Jupyter, as the instructions said it’d happen

The first time you run notebook() , it will prompt you for whether it should install Jupyter. Hit enter to have it use the Conda.jl package to install a minimal Python+Jupyter distribution (via Miniconda) that is private to Julia (not in your PATH )

Instead, using notebook() opened a new tab on my browser for local Jupyter notebooks. In this tab, I can see folders like “Desktop” and “Documents” from my computer. In the Julia REPL, an information session was printed. It starts with [ Info: running setenv(`'C:\Users\hsd36\.julia\conda\3\Scripts\jupyter.exe' notebook`,["PATH=C:\\Users\\hsd36\\.julia\\conda\\3\\Library\\bin;, but it goes on.

Seeing no way to solve this, I followed ahead and installed Revise.jl and Conda.jl, and finished with Conda.add("jupyter-cache").

Then I tried quarto render test_quarto.qmd in a Powershell terminal, but it failed. It first says it’s starting the julia-1.8 kernel and then a list of files is listed. It ends with an error: ImportError: DLL load failed while importing _device: The specified module could not be found. When I simply try CRTL + Shift + K, a Quarto Preview terminal opens and informs me that Jupyter kernel 'julia-1.8' not found.

Does anyone know how to proceed from here? It seems the problem lies in the missing kernel. Ideally, I’d install a minimal Python distribution via Miniconda that is private to Julia. This installation should have been offered after the command notebook(), but sadly it didn’t.

Edit: I have checked the answers for a very similar question here in the Discord, but it was to no avail.

Edit 2: Here’s the output after I ran quarto check.

In other words, Jupyter is already installed. You are running the notebook, congratulations!

:slight_smile: I actually managed to locate the julia-1.8 kernel, but I still don’t know how to pass the path to Quarto.
