Hello, I am new to Julia, and I recently downloaded JuliaPro 1.0.5 on a new computer. However, I ran into trouble with Pkg.add() just into the third line, and none of the threads on julialang.org, stackexchange or GitHub solved my problem.
The error messages are:
julia> Pkg.add("GraphPlot")

I have tried removing the ~/.juliapro/JuliaPro_v1.0.5-2/registries/General
folder, changing its permission with chmod -R 755
, but the error stays the same. I would appreciate it if you could point me to a relevant thread.
