Install IJulia on Julia 1.0.0 - julia

Question

I just installed Julia and would now like to install the IJulia notebook. However, compilation fails:
julia> Pkg.build("IJulia")

What's wrong?
Update: regarding the concernes with the .julia/packages/Conda/m7vem/deps/usr/ folder, all appears correct:
$ ll /home/user001/.julia/packages/Conda/m7vem/deps/usr/
