8 months ago I have no idea, why this happens. I don't think, that there are name conflicts (GR vs GRB).
Could please find the missing library (find ~/.julia/artifacts -name libgurobi100.dylib) and try the following command:
otool -L <path from above find command>libgurobi100.dylibYou could also try to run the otool command within your Julia session.

8 months ago For some reason I cannot find the Gurobi library in my artifacts folder (or any .dylib file with gurobi in the name).
eetureijonen@Eetus-MacBook-Air artifacts % find ~/.julia/artifacts -type f \( -name "*gurobi*" -a -name "*.dylib" \)
I found it in my /Library folder and this is the output from the otool-command.
eetureijonen@Eetus-MacBook-Air lib % otool -L /Library/gurobi1001/macos_universal2/lib/libgurobi100.dylib

julia ...Thank you, this seems to solve the acute problem for me.

Hi, I have run into a weird issue when trying to use Plots.jl with GRBackend and Gurobi.jl (the optimization solver) with multiple workers.
The minimal working example is here:
This code will produce an error, which, according to my understanding, indicates that the Gurobi library/program cannot be found.
However, by using a different backend (e.g. PyPlot), the code works just fine:
Output:
I'm using Julia version 1.9.1, Plot.jl v1.39.0, Gurobi.jl v1.2.1 on a Macbook M2 Air with macOS 14.2
Could this issue be caused by some kind of alteration to the system environment before it's passed to the workers? Or possibly a namespace conflict (Gurobi is also abbreviated GR in some contexts)?
