Starting with Julia 1.10, you can manage versions using juliaup. Use the juliaup default <version> command to set the default Julia version used on that computer.
From the command line
julia +<version>
By appending a plus sign and the version directly after the julia command, you can run that specific version.
In VS Code
{
"julia.executablePath": "${env:USERPROFILE}\\.julia\\juliaup\\julia-1.11.6+0.x64.w64.mingw32\\bin\\julia.exe"
}
Add the julia.executablePath option as shown above to the .vscode/settings.json file in the directory you’re running. Typically, Julia binaries installed via juliaup are stored under the user profile at .julia\juliaup, so set the exact path to the binary you want to force VS Code to use.
