Hello I am new in Julia and i would like your help on how to manage differents package that are compatible with differents versions. I found this error when using the DataDrivenDiffEq Pkg.

Also note I’m using Julia 1.8.

Thanks in advance

Don’t install your packages (other than maybe dev dependencies like `Revise`, `BenchmarkTools` etc) in the default environment, work with project specific environments instead:
