I wanted to try out quarto for Julia code.

1. I created an new Julia environment `q` and installed `IJulia.jl` and `Plots.jl`

2. The `jupyter kernelspec` & `quarto check` all seem fine.

3. when trying to render Julia example [Using Julia – Quarto](https://quarto.org/docs/computations/julia.html) it gives error message

```julia-auto
C:\julia110>quarto render jex.qmd
Starting julia-1.10 kernel...ERROR:

Kernel died before replying to kernel_info

```

1. How do I make jupyter and quarto use `IJulia` from the `q` project environment from the CLI?

Yes, I did that much before.

</div>

After a lot of fiddling, the reason for this error is that when `IJulia` installs the jupyter kernel, it sets the project path to default i.e. `--project=@.` in the `C:\Users\julius\AppData\Roaming\jupyter\kernels\julia-1.10\kernel.json` file

```julia-auto
jupyter kernelspec list

julia-1.10 C:\Users\s\AppData\Roaming\jupyter\kernels\julia-1.10

```

We need to manually alter the file to change the project to the one we want as shown below. We have replaced `--project=@.` with `--project=q`

### kernel.json

```json
{
  "display_name": "Julia 1.10.0-DEV",
  "argv": [
    "c:\\julia110\\bin\\julia.exe",
    "-i",
    "--color=yes",
    "--project=q",
    "c:\\julia110\\.julia\\packages\\IJulia\\AQu2H\\src\\kernel.jl",
    "{connection_file}"
  ],
  "language": "julia",
  "env": {},
  "interrupt_mode": "message"
}

```

### original kernel.json

```json
{
  "display_name": "Julia 1.10.0-DEV",
  "argv": [
    "c:\\julia110\\bin\\julia.exe",
    "-i",
    "--color=yes",
    "--project=@.",
    "c:\\julia110\\.julia\\packages\\IJulia\\AQu2H\\src\\kernel.jl",
    "{connection_file}"
  ],
  "language": "julia",
  "env": {},
  "interrupt_mode": "message"
}

```

Now both `quarto` and `jupyter` are able to find `IJulia`.

I have the same issue, but setting `--project=q` does not solve the problem for me on Linux (Btw: what does it mean?). IJulia works inside Julia REPL, and quarto check also says ok:

```julia

      The rmarkdown package is not available in this R installation.
      Install with install.packages("rmarkdown")

```

However I don’t encounter the issue on my Win11 laptop.

> setting `--project=q` does not solve the problem for me on Linux (Btw: what does it mean?)

TLDR: I guess I didn’t explain properly above but `q` is the name of the Julia project I created inside which I did install IJulia. You should substitute with the project name where IJulia is installed.

## Longer Explanation:

A Julia ‘project’ is equivalent to a conda ‘environment’. It is a self-contained directory contains your specific packages.

1. After starting julia, if you type `]`, it should take you to the package mode.
2. Here you should see something like `(@v1.10) pkg>` depending on your version. This is the default project environment of Julia. This corresponds to `--project=@.` in the JSON kernel file.
3. How this works inside Julia REPL is that:  
`]activate .` opens the current directory as the project environment.  
`]activate` opens the default julia project as the project environment.  
`]activate projname` opens the projname project as the project environment.
4. Say you created a project named `ijuliaproj` and installed IJulia in it, then you should use `--project=ijuliaproj` in the kernel JSON file.

Hope this helps some more. Let me know if you have any further difficulties. 👍

Thanks for the explanation! But I guess if I install IJulia not inside my project but in global Julia environment, this should not matter?

I found [this issue](https://github.com/quarto-dev/quarto-julia/issues/3) reported in the quarto repo.

These are two independent issues as far as I know.

1a. If IJulia is installed in the default environment, then you don’t need to tinker with the kernel JSON.

1b. If IJulia is installed in a project say `qq`, then you need to specify `qq` in the kernel JSON

2a) The kernel not starting was an IJulia problem because it only recognized till Juliav1.8. It gave that error for Juliav1.9 & Juliav1.10. We complained and it was finally fixed in [Kernel does not start with Julia 1.9 · Issue #1062 · JuliaLang/IJulia.jl · GitHub](https://github.com/JuliaLang/IJulia.jl/issues/1062)

2b) Now your issue is for quarto+IJulia. It could be a Linux issue. IDK.

For me the Windows 10, IJulia installed in `qq` project. So quarto works for the example in the Quarto website: [Using Julia – Quarto](https://quarto.org/docs/computations/julia.html)

It’s definitely not easy when the workflow consists of many tools!!

Just a quick update, since it hasn’t been discussed here anymore:

This bug is fixed in Quarto 1.3.
