I am trying to use `Quarto` to render the following known example file (`ex2_Julia.qmd`):

````julia
---
title: "Plots Demo"
author: "Norah Jones"
date: "5/22/2021"
format:
  html:
    code-fold: true
jupyter: julia-1.8.0

## Parametric Plots

Plot function pair (x(u), y(u)).
See @fig-parametric for an example.

```{julia}
#| label: fig-parametric
#| fig-cap: "Parametric Plots"

using Plots

plot(sin,
     x->sin(2x),
     0,
     2π,
     leg=false,
     fill=(0,:lavender))

````

I have no problems when using the Python version, but when I do the following command on the terminal (Mac), I get an error:

```julia
❯ quarto render ex2_julia.qmd
ERROR: Jupyter kernel 'julia-1.8.0' not found.

```

I don’t understand why the kernel is not found. I added `IJulia`.

What is the output of `jupyter kernelspec list`?

When you installed IJulia did you modify `ENV["PYTHON"]` to work in the same Python environment as Quarto?

See [GitHub - JuliaPy/PyCall.jl: Package to call Python functions from the Julia language](https://github.com/JuliaPy/PyCall.jl#specifying-the-python-version)

Did you try `julia-1.8`

You’re right:

```julia
Available kernels:
  ir /Users/sergiobacelar/Library/Jupyter/kernels/ir
  julia-1.6 /Users/sergiobacelar/Library/Jupyter/kernels/julia-1.6
  julia-1.7 /Users/sergiobacelar/Library/Jupyter/kernels/julia-1.7
  python3 /Users/sergiobacelar/Library/Jupyter/kernels/python3
  octave /Users/sergiobacelar/anaconda3/share/jupyter/kernels/octave

```

There is no `julia-1.8.0` kernel. How can I modify the `ENV`? I am using Anaconda and I have a `base` env. I tried `conda deactivate` but I think it didn’t work.

Yes. Same error.

In Julia REPL (plz make sure you are running Julia 1.8)

```julia
using Pkg
Pkg.build("IJulia")

```

This command should register the` julia-1.8` kernel.

Just to be sure, you can run `jupyter kernelspec list` to see if `julia-1.8` kernel is installed.

Edit: And as @mkitti suggested, please make sure IJulia is using the same python environment as quarto is.

Try this in julia.

```julia
ENV["PYTHON"] = "/path/to/python/used/by/quarto"
using Pkg
pkg"add PyCall"
pkg"build PyCall"
pkg"add IJulia"
pkg"build IJulia"

```

You can determine the path to quarto’s Python using `which python`.

I think I found the solution:  
`build IJulia`

I see that `build` fixed your issue, but I wanted to put this here in case somebody else has a slightly different issue. I had a weird case were Quarto was picking up a different python version than what was on my path without me knowing. It was using some random conda env version. In that case `build` didn’t work b/c it wasn’t registering with the correct Jupyter install.

In that case , I was able to debug things using `quarto check`

This looks like it changed recently:

> Use IJulia’s built-in conda environment / jupyter install for julia notebooks/qmds  
> [https://github.com/quarto-dev/quarto-cli/blob/v1.1.120/news/changelog-1.1.md?plain=1#L10](https://github.com/quarto-dev/quarto-cli/blob/v1.1.120/news/changelog-1.1.md?plain=1#L10)

In older versions I had to set `QUARTO_PYTHON` to my IJulia conda `c:\Users\username\.julia\conda\3\python.exe`, since I don’t have `python` in my path.

Thank you SO much for this suggestion. I’m in Python environment hell, and your suggestion showed that for whatever reason, `Quarto` couldn’t find my `Jupyter` installation.

Where do I run this command?

Any recommendations in case the accepted solution does not work? Quarto was working fine for me, but I just updated to a newer version of Julia (1.8.5), and maybe this has “broken” something.

This seems to be an issue with Julia \> 1.8.3 and it has been reported in the quarto-cli repository:

latest activity there 10h ago, so I guess it’s actively worked on.

Basically, if you install and build `IJulia` with julia version \> 1.8.3, it will not work (I tested only with 1.8.5). I removed `IJulia` and re-installed and rebuilt it using 1.8.3 and it worked.
