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](https://github.com/jump-dev/Gurobi.jl)

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

Anyone can help me please?

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

Are you using a custom repository, like 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.
