I downloaded Julia binary and simlinked as `julia-1.0.1`.  
When I try to add packages, the following error:

```julia

Looks like a bug, could you open an issue at [https://github.com/JuliaLang/Pkg.jl](https://github.com/JuliaLang/Pkg.jl).

I deleted all of the .julia directory and the used REPL with julia to load in  
packages; this reconstructed most of everything in the new .julia directory.

You may need to add packages as you try new code.
