NEED HELP: Warnings/errors from "Pkg.add("GLPKMathProgInterface")

New to Julia
1

I’m on a MacBook Pro running High Sierra. I’m trying to run the following code in Julia - https://github.com/dscotthunter/Fantasy-Hockey-IP-Code

I download Julia, and enter the following commands:

Pkg.add(“JuMP”)
Pkg.add(“DataFrames”)

and those run smoothly…but when I enter "Pkg.add(“GLPKMathProgInterface”) I get the following readout - can someone help me figure out how to do this properly? Thanks in advance!:

julia> Pkg.add(“GLPKMathProgInterface”)

Well I uninstalled Julia and got rid of all traces of the packages and everything, reinstalled everything and it worked fine. Mods can delete this or whatever they’d like as I am up and running. Thanks.
