Macromodelling package issue

[laurencejj]

Hi, I would love to use your package as it looks really useful. However, I am having issues getting it working, when I install it:

ERROR: LoadError: MethodError: no method matching AbstractDifferentiation.ForwardDiffBackend()
The type `AbstractDifferentiation.ForwardDiffBackend` exists, but no method is defined for this combination of argument types when trying to construct it.

I always get the following error:
✗ ImplicitDifferentiation → ImplicitDifferentiationForwardDiffExt as your package is relying on ImplicitDifferentiation v0.5.2, however it is now at version 0.6.3 and even removing and installing the earlier package causes issues.

Error: Error during loading of extension ImplicitDifferentiationForwardDiffExt of ImplicitDifferentiation, use `Base.retry_load_extensions()` to retry.
│  │   exception =
│  │    1-element ExceptionStack:

and

ImplicitDifferentiation [57b37032] log:

 └─restricted by compatibility requirements with MacroModelling [687ffad2] to versions: [0.2.0 - 0.3.0, 0.5.0 - 0.5.2] — no versions left

Please let me know how I can get it working! Thanks!!

fixed by proper project package management

Thanks for posting.

You should be able to safely ignore the precompilation error. I tested a fresh install and it works as intended despite the precompilation error. The upcoming release will fix the precompilation error.
