Julia-vscode: Could not start the julia language server. Make sure the configuration setting julia.executablePath points to the julia binary.

[scls19fr]

Hello,

I'm using Ubuntu Linux 17.10

Julia is installed in my home directory and I have a symbolic link which point to Julia binary.

$ ls -la ~/bin/julia 
lrwxrwxrwx 1 scls scls 37 nov.   3 17:48 /home/scls/bin/julia -> /home/scls/julia-0d7248e2ff/bin/julia

~/bin is in my PATH

scls@scls-Skylake:~$ julia --version                                                                                                                                                                                                                  
julia version 0.6.1

After installing Visual Studio Code and Julia extension the following message is displayed when editing a .jl file.

Could not start the julia language server. Make sure the configuration setting julia.executablePath points to the julia binary.

(despite Julia binary is in my PATH)

I also edited user settings with

{
    "julia.executablePath": "~/bin/julia"
}

but I'm still getting the error message

Could not start the julia language server. Make sure the configuration setting julia.executablePath points to the julia binary.

I also tried

{
    "julia.executablePath": "/home/scls/bin/julia"
}

and

{
    "julia.executablePath": "/home/scls/julia-0d7248e2ff/bin/julia"
}

without positive results

Any idea?

Kind regards

[davidanthoff]

@ZacLN, any idea? I'm not a Linux expert...

[ZacLN]

have you tried just "julia.executablePath": "julia"?

[quendera]

Did you solve this @scls19fr ?

[scls19fr]

I put

{
    "julia.executablePath": "/home/scls/julia-0d7248e2ff/bin/julia"
}

it's working now (I don't understand why it wasn't working previously)

Thanks @quendera @davidanthoff and @ZacLN

[igoobud]

Okay, I know this is closed but I just had the same and what fixed it was after updating my settings, I literally closed VS code and opened it again.

[scls19fr]

I also think that it is what fixed my issue.

[JackHo327]

Met the same situation here and I am on the mac.

> which julia
julia: aliased to /Applications/Julia-1.0.app/Contents/Resources/julia/bin/julia

my configuration is:

"julia.executablePath":"/Applications/Julia-1.0.app/Contents/Resources/julia/bin/julia"

[davidanthoff]

Julia 1.0 is not yet supported.

[JackHo327]

Hi @davidanthoff , thanks for your information. Will keep an eye on this good extension.

[wpwoodjr]

@davidanthoff When will Julia 1.0 be supported by the extension? Why wasn't it released as part of the 1.0 release?

[davidanthoff]

I don't know when we will be done with the 1.0 extension. It was not released as part of 1.0 because this is all done by volunteers and we are busy and didn't have the time to finish things earlier.

[iambudi]

Julia Language Server is busy.

[wassimoo]

Still not working on 1.0 release

[jcbritobr]

Not work with current release of julia :(

[AndroxxTraxxon]

Still not working on the 1.0.1 release.

[kraftpunk97]

@davidanthoff Hi. Is 0.7 supported? Because I seem to get the same issue on v0.7 as well.

[drdh]

I got the same problem on the 1.0.1 release.

[eugene2017]

me too,my version is 1.0.2

[therimalaya]

Same problem with 1.0.3, is there any news for the problem?

[davidanthoff]

What version of the extension are you using? We have a beta here that should work with julia 1.0.x. The one you get from the VS Code marketplace does not yet work with julia 1.0.x.

[xximranxx]

Not working for me on OS X with the following setting (julia 0.6.4):
"julia.executablePath": "/Applications/Julia-0.6.app/Contents/Resources/julia/bin/julia"
When restarting VS Code, I get the same error

[davidanthoff]

The v0.11.x version of the extension only works with julia 1.0 and newer. If you want to use julia 0.6, you need to install an older version of the VS Code extension. There should be an option in the VS Code UI for that.

[kasperfred]

Do you have an ETA on when julia 1.0 will be supported?

[davidanthoff]

Yes, we published the julia 1.0 compatible version a while ago.

[kasperfred]

Oops.
Just pretend I never said that.

[LaszloHars]

In the Julia REPL console, I added the JSON package. After starting VS Code I edited the julia.executablePath to C:/t/Julia/bin/julia.exe (for my case) - yes, with forward slashes even in Windows. There was no more error "Could not start the julia language server".

[jingpengw]

I still have this problem with Julia 1.0.4.

[davidanthoff]

I think you need the master version of all the packages here in the julia-vscode org for things to work. We'll tag new versions of all the packages once we release the next version.

[nakulrandad]

I have the same problem.
My settings.json file is:
{ "julia.executablePath": "~/snap/bin/julia", "workbench.startupEditor": "newUntitledFile", "julia.enableTelemetry": true }

usr@usr-ubuntu:~$ which julia
/snap/bin/julia

How can I resolve this issue?

[davidanthoff]

Which seems to suggest that your julia is in /snap/bin/julia, but you have configured ~/snap/bin/julia?

[nakulrandad]

Which seems to suggest that your julia is in /snap/bin/julia, but you have configured ~/snap/bin/julia?

Yep, resolved ✌🏻

[spcogg]

For me everything was working fine, then suddenly I would get the 'LS not started' error, and in the output for Julia Language server it would just hang with no feedback. (see screenshot)

@jingpengw 's screenshot helped me (Always post screenshots guys!), I ran the ' add LanguageServer' command in pkg manager, and restarted vscode, all of a sudden the languageserver is back. Not sure how it got uninstalled in the first place?

Found that languageServer was missing, then installed it. Not even sure how Julia was accepting alt-enter before this.

[davidanthoff]

You don't need to install the language server package for VS Code, and if you do install it, VS Code will just ignore that version. In general, you don't need to install any Julia packages for the VS Code extension to work, we ship everything we need as part of the extension and never install anything into your user Julia environments.

@spcogg the first screenshot you posted just means that the language server was still starting.

[Benefit-Zebra]

Hello @davidanthoff

I am on Windows 10.

VS code version 1.44.2
Installed Julia extension version 0.15.28

I installed VS Code on my local disk D.
It is also showing same error of "Could not start the julia language server. Make sure the configuration setting julia.executablePath points to the julia binary."

julia.exe was nowhere to be found when I tried to search for it

[davidanthoff]

Just download Julia from julialang.org and install it into the default directory, then the VS Code extension should find it automatically.

[Benefit-Zebra]

When I try to run file:

When I click on launch.json:

I am getting this error

[davidanthoff]

I thought the error was Could not start the julia language server. Make sure the configuration setting julia.executablePath points to the julia binary? Are you still getting that error as well?

[Benefit-Zebra]

Thanks @davidanthoff .Yup! your idea of downloading "_Julia from julialang.org and install it into the default directory_" worked and hence i was no longer getting Could not start the julia language server. Make sure the configuration setting julia.executablePath points to the julia binary.

So then as issue was solved, I tried to run the file and I got error command 'language-julia.debug.getActiveJuliaEnvironment' not found

[davidanthoff]

@Benefit-Zebra ok. Could you open a new issue with the language-julia.debug.getActiveJuliaEnvironment problem? That is distinct from what this issue here is about.

[Benefit-Zebra]

@davidanthoff Ok I am opening a new issue.
