Lyapunov example won't run, incremental compile problem during package installation?

[tjr1]

Hi. First, thanks for developing FractionalDiffEq. It is awesome. I'm trying to use it for a research project.

Issue: When I try to run the Lyapunov exponent example https://scifracx.org/FractionalDiffEq.jl/dev/flyapunovexp/ , I get an error: "MethodError: no method matching" for FOLyapunov()

Initially, I was running it in JuliaHub with Julia 1.8.5, then I tried it locally on my mac with Julia 1.9.1.

Maybe related:
I noticed when I installed the FractionalDiffEq package locally, that it gave warnings about FOLyapunov() and a number of other functions: "** incremental compilation may be fatally broken for this module **"

Did some google searches and found that this has popped up variously for others:

Maybe the new manifest features from 1.7 are causing probems. Would an older version of Julia solve this? Like 1.6 or something?

Wondering if you've seen this and what you might suggest.

Gratefully,
Tom

I tested it out on Julia 1.6.7, the LTS version, and it worked perfectly. So I'm guessing this is an issuing with >= Julia 1.7. Should we close the issue then?

Sorry for the errors and late response, FractionalDiffEq.jl is undergoing an extensive overhaul, so some features may be broken, it is great you figured out the problem. I think we can keep this issue open until all things are done.
