Anyone knows what it could be?
Thanks in advance.

I believe that Clp is having some compability issues with Julia 1.2.0 or JuMP 0.20. With the latest Julia and JuMP version, I have the exact same issue.

Clp has not been updated to the latest JuMP version. Use JuMP 0.19.

I used Pkg.add(PackageSpec(name = “JuMP”, version = “0.19.0”))

I have tried to install JuMP 0.19 as suggested, but I got the following error:

Anyone got the same problem or have an idea about this?
