I tried the following so far.

```julia
julia> import Pkg

julia> Pkg.add("pyeval")
  Updating registry at `~/.julia/registries/General`
  Updating git-repo `https://github.com/JuliaRegistries/General.git`

I think that `pyeval` needs to be installed in Python. This is not a Julia package.

Once installed in python, you can then call the functions in pyval with PyCall.jl package.
