DiffEqTutorials not working in Julia 1.5.0

Hi all,

I’ve decided to give differential equations a go, and wanted to follow along with the notebooks, I have Julia 1.5.0 installed. The documentation for DifferentialEquations.jl says to run

using Pkg
pkg"add https://github.com/JuliaDiffEq/DiffEqTutorials.jl"
using DiffEqTutorials

but I get

julia> using Pkg

julia> using DiffEqTutorials
ERROR: ArgumentError: Package DiffEqTutorials not found in current path:

I did as the error message said, i.e. import Pkg; Pkg.add("DiffEqTutorials") but then I get:

I’ve also tried SciMLTutorials but I get a similar error.

This is an upstream issue with Weave.jl that we notified the developers about.
