Error importing Base

[bdas123]

I installed PyJulia using the instructions provided here.

When I run the following commands, I get a JuliaError:

import julia
julia.install()
from julia import Base

JuliaError: Exception 'ArgumentError' occurred while calling julia code:
const PyCall = Base.require(Base.PkgId(Base.UUID("438e738f-606a-5dbb-bf0a-cddfbfd45ab0"), "PyCall"))

[mkitti]

Try running

using Pkg
pkg"add PyCall"
pkg"build PyCall"

[mkitti]

I suspect this is the trace.

julia> const PyCall = Base.require(Base.PkgId(Base.UUID("438e738f-606a-5dbb-bf0a-cddfbfd45ab0"), "PyCall"))
ERROR: ArgumentError: Package PyCall [438e738f-606a-5dbb-bf0a-cddfbfd45ab0] is required but does not seem to be installed:
 - Run `Pkg.instantiate()` to install all recorded dependencies.
