Problem installing and using QuantEcon library

[kderkba]

Hi,
When i Try to use QuantEcon library by typing "using QuantEcon" I get the following error: failed to precompile QuantEcon to..."
And it says:
ERROR: LoadError: FFTW is not properly installed. Please run Pkg.build("FFTW") and restart Julia.

When I try to build FFTW I get an other error (images below)

What happens if you run import Pkg; Pkg.add("FFTW") as instructed and then Pkg.build("FFTW")?

I get an Error: Error building FFTW. (image below)

Sorry, it's saying import Pkg; Pkg.add("Pkg"). What happens if you just run import Pkg?

[kderkba]

It does the same thing. I am able to run import Pkg; Pkg.add.("Pkg") (I also find this a bit counter intuitive, how can I add "Pkg" from Pkg.add?)

But basically I have Pkg, and when I try to run build FFTW it gives the same error as before.
