I am using Julia 1.8.5 in VSCode on Windows. I just started a new environment using import Pkg Pkg.activate("math", shared=true) Then I tried to install DifferentialEquations, but got the following error: Precompiling DifferentialEquations [0c46a032-eb83-5123-abaf-570d42b7fbaa] ERROR: LoadError:…

I have the same issue in Julia 1.9.3, however someone has created an issue on SimpleNonlinearSolve.jl. If you want an immediate way to run your notebook, downgrading SimpleNonlinearSolve from v0.1.24 to v0.1.23 avoids this precompile issue for me.

A lower bound was added and this version was yanked from the registry. If you update you should be good. Sorry about that, the release just needed better lower bounds.
