When I try to compile my Julia file in a Julia command prompt, as so :
julia> include("file.jl")
it shows me this error, which I can't wrap my head around :
[ Info: Precompiling PyPlot [d330b81b-6aea-500a-939a-2ce795aea3ee]

How do I solve this? I note that I have installed PyPlot :
julia> import Pkg; Pkg.add("PyPlot")

I also note that I am getting this error in a second Julia command window using Juno, since Juno's standard REPL is occupied running some other code. This other code in REPL includes my "faulty" files file.jl, file2.jl and file3.jl as well, and runs just fine there.
The problem solved itself after I tried to open a second REPL by clicking in the menu bar Juno -> Open External REPL, instead of my initial Juno -> New Terminal -> Current File's Folder.
