I’m using DifferentialEquations on a pixelbook and I’m getting the following issue:

I’m completely lost, what do I do here?

How did you install Julia? It looks like you may still be on Julia 1.5 which I don’t belive is supported by DifferentialEquations.jl anymore. (Ideally DifferentialEquations.jl would declare this in its Project.toml though so an older compatible version is installed instead.) You should download the latest Julia binaries from [Download Julia](https://julialang.org/downloads/) instead.

Thanks @simeonschaub, that was exactly the issue. I reinstalled Julia at 1.7.3 and all is working smoothly now.
