Julia1.0 has just been installed and I want to take the first step:
Pkg.add("PyPlot")
ERROR: ERROR: UndefVarError: Pkg not defined
Problem description:
Since Julia’s extension pack is installed using a Pkg extension pack, you must import Julia’s extension pack Pkg before installing the extension pack
Solutions:
Import the Pkg package
Then use the pkg. add() command
using Pkg
Pkg.add("Packagename")
