Error with dependency of NetworkDynamics.jl. What to do?

I am trying to run this BlockSystems.jl example but I’m getting an issue with what seems like a dependency of NetworkDynamics.jl.

#=
## Integration with `NetworkDynamics.jl`
In this example we model a Network based on the [Kuramoto model](https://en.wikipedia.org/wiki/Kuramoto_model) using the [`NetworkDynamics.jl`](https://github.com/FHell/NetworkDynamics.jl) package.
=#

using NetworkDynamics
using Graphs
using BlockSystems
using ModelingToolkit
using OrdinaryDiffEq
using Plots

#=
In the Kuramoto model each vertex $i$ has it's own intrinsic angular frequency $\omega_i$.
The angle of frequency is given by
```math
\dot\phi = \omega_i + \sum e
```
where $\sum e$ sums over all the connected edges.

Can someone help me make sense of it and point to the solution?
