Problems in the Gurobi installation

Dear all,
I have the Gurobi software on my computer.
I want to install the Gurobi package in Julia. I have followed the steps on GitHub - jump-dev/Gurobi.jl: Julia interface for Gurobi Optimizer

An error message appears when I try Pkg.add("Gurobi"). See below:

Anyone can help me please?

Works for me - can you install any packages?

Any packages!!!

Could you share the output of versioninfo() ? Also, does it help if you do Pkg.update() ?

Are you using a custom repository, like JuliaPro?

yes, JuliaPro.

JuliaPro is often a source of this kinda of problem. I cannot really think about a situation in which I would recommend using it.

The solution was to delete the folder ~.julia.
Many thanks.
