Error while calling Julia from R: R version: 4.3.1, Julia version is 1.9.2.

[yevgenryeznik]

When I try to run the command:

JuliaCall::julia_setup()

I get the following error:

Julia version 1.9.2 at location /Applications/Julia-1.9.app/Contents/Resources/julia/bin will be used.
Loading setup script for JuliaCall...

To have more helpful error messages,
you could considering running the command in Julia directly

Your issue is a duplicate of #203. TL:DR; a fix has been identified and will appear on CRAN eventually. To get the change now, either add @eval to the front of line 77 of JuliaObject.jl yourself or install JuliaCall using the devtools package.
