Trying to use Dataframes, just getting started

Can you tell me what’s up with my Julia 1.0.0 installation?

I installed Julia into /usr/share/bin of my fresh KDE Neon install. I updated and reloaded my .bashrc file so I can load Julia from the terminal.

At the Julia command prompt I tried:

using Pkg
Pkg.add(“Dataframes”)

and I get this…
Updating registry at ~/.julia/registries/General
 Updating git-repo https://github.com/JuliaRegistries/General.git
ERROR: The following package names could not be resolved:

  • Dataframes (not found in project, manifest or registry)
    Please specify by known name=uuid.
    Stacktrace:
    [1] pkgerror(::String) at /buildworker/worker/package_linux64/build/usr/share/julia/stdlib/v1.0/Pkg/src/Types.jl:120

etc

Capital F for DataFrames?

I guess since Julia has the registry information it could (and should) indicate such a potential typo.
