Could not start the julia language server in VS Code

I'm getting this error in VS Code:

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

In user settings I put

"julia.executablePath": "c:\\Program Files\\Julia\\Julia-0.5.0\\bin\\julia.exe"

which is a correct executable path.

Julia works without a problem in console and VS Code worked fine with older extension 0.4.2. I've tried reinstalling both the extension and VS Code, but it didn't help.

What am I doing wrong?

It is probably due to a SysImage you have compiled and replaced the original sys.dll file with that. Try to check the path C:\Users\User\AppData\Local\Programs\Julia-1.7.3\lib\julia or any other path you have installed Julia and see if a sys.dll.backup exists there, together with a sys.dll file. Rename the sys.dll to sys.dll.old and rename the sys.dll.backup to sys.dll. Then restart julia or VS Code.

I had the same problem, just run Julia REPL and switch to pkg mode with ] and add LanguageServer package with add LanguageServer and restart vs code.

Have a look if the 'LanguageServer' package is actually installed/somehow uninstalled, this happened to me. After manually installing it, it was all fine and dandy again.

Indexing all the packages still takes ages, though.

Reinstalling Julia solved this for me, I tried the previous answers

This can happen if the VS Code extension doesn't support the current version of Julia.

Also check that the path is pointing to the julia.exe executable inside the bin folder.

C:\Users\yourname\AppData\Local\Julia-0.5.0\bin\julia.exe

because there is also another one that doesn't work.

C:\Users\yourname\AppData\Local\Julia-0.5.0\julia.exe

VS Code settings don't seem to always play nice with backslashes. Try instead single slashes, even on Windows:

"julia.executablePath": "c:/Program Files/Julia/Julia-0.5.0/bin/julia.exe"

It may, however, also be a problem with the blank in 'Program Files', in which case the legacy 8.3 filename convention could work:

"julia.executablePath": "c:/PROGRA~1/Julia/Julia-0.5.0/bin/julia.exe"

Note that you would typically have both 'C:\PROGRA~1' and 'C:\PROGRA~2' pointing to 'C:\Program Files' and 'C:\Program Files (x86)', respectively. Find the correct one from the console.
