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](https://diffeq.sciml.ai/stable/#IJulia-Notebook-Tutorials-1) says to run

```julia
using Pkg
pkg"add https://github.com/JuliaDiffEq/DiffEqTutorials.jl"
using DiffEqTutorials
DiffEqTutorials.open_notebooks()

```

but I get

```julia
julia> using Pkg

julia> pkg"add https://github.com/JuliaDiffEq/DiffEqTutorials.jl"

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:

```julia

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.
