Note that that is just complaining about the implicit import from Base. If you do using Pkg first, then Pkg.add will work as before (but use the new package manager). See - YouTube for more.
you type dev MyPackage into the Pkg repl and it’ll get you a git clone of it into ~/.julia/dev/MyPackage. In particular, you should no longer edit packages in situ without deving them first, because the package manager is in charge of non-dev packages.
