Visual Studio is a powerful integrated development environment (IDE) developed by Microsoft, widely used for various types of software development. It supports a wide range of programming languages, including C#, C++, Python, JavaScript, TypeScript, and many others, making it versatile for different projects.
Using Julia in Visual Studio Code (VS Code) provides a robust environment for developing Julia applications.
VS Code may give the following error when using the Julia language server:
Could not start the Julia language server. Make sure the configuration setting julia.executablePath
points to the Julia binary.
The above error means that the julia.exe
can not start the language server, and it suggests checking if julia.executablePath
points to the Julia binary.
Following are some steps you can take to troubleshoot this problem:
Install/Re-install: Make sure the Julia extension is installed in the VS Code. Re-installing also helps sometimes. For reference, you can review the documentation on the website of VS Code.
Compatibility issues: Make sure Julia and VS Code are updated. Try using the latest versions.
Check the path: Verify that the Julia executable is in the system’s path. You can also manually set the path to the Julia.exe
in the VS Code. For this, go to “File"→"Preferences"→"Settings”. In the search bar, type julia.executablePath
. Click the “Edit in settings.json” link. Now, add the julia.executablePath
setting with the path to the Julia executable in the settings.json
file. Modify according to the path where Julia is installed.
For Windows:
{
"julia.executablePath": "C:\\Path\\To\\Julia\\bin\\julia.exe"
}
For Linux/MAC:
{
"julia.executablePath": "/path/to/julia/bin/julia"
}
Check the language server output: Select "View" → "Output" and choose "Julia Language Server" from the dropdown. Look for any error messages or warnings.
Add the language server: Open Julia in the terminal and switch to pkg
mode with ]
and add the LanguageServer
package with add LanguageServer
command and restart VS code.
pkg
mode with ]
and update the LanguageServer
package with the update LanguageServer
command and restart VS code.(@v1.4) pkg> update LanguageServer
