I had Jupyter working for the first time yesterday, and was able use the latest version of Julia Pro, to run most files. Today though, It says something about unable to spawn ENOENT, and none of the features work.

Brett, you need to supply more information for people to be able to help you. At the absolute minimum, showing us the actual error message will go a long way.

Sorry about that. At first I didn’t realize the error was available. I did find the error and added it to my message.

Can you open a julia repl and type `using Pkg; pkg"st IJulia"` for me?

The output should look something like

```julia
julia> using Pkg; pkg"st IJulia"
Status `~/.julia/environments/v1.5/Project.toml`
  [7073ff75] IJulia v1.21.3 ⚲

```

Also, could you show `versioninfo()`? For me, this looks like

```julia
julia> versioninfo()
Julia Version 1.5.3

You should be familiar with when you need to do `using Pkg` before performing package commands. You are aware that in order for `Pkg.add("IJulia")` to work you first have to run `using Pkg` or `import Pkg`?

yes, I imorted IJulia, and I loaded IJulia, using the ‘using’ function.

I did get several warning though.

```

they’re all related to the server, which might explain why problems involove new notebooks or exporting

No, I meant `using Pkg` as I said.

No I hadn’t the error about spawning went away. Now I have one about nbconvert

```julia

I tried to install nbconvert with conda, and it said it was already installed.

Run `import Pkg; Pkg.build("IJulia")` again.

I’m not sure what this ENOENT that it’s trying to connect to is.

I was using mouse commands, I’ll try some keword commands and get back to you. So far, I’m able to get to the save window, but when I press the export button, I get a notice that the export has failed.

It seems like the jupyter mode (which was just recently released) is not workig as promised using VS Code.

Unfortunately this _probably_ isn’t a julia problem, but rather a VS Code problem.

However I notice you are using Julia Pro. Maybe try downloading the normal binaries of Julia instead.

Ok, I can try that. I thought it started with Julia Pro, but now when I look at the options, the old option is Julia 1.4.0 . I can try that. I have 1.5.3 so I should be able to set up an environment path.
