Error in using Optim with Julia v1.0: ERROR: LoadError: LoadError: UndefVarError: InPlaceObjectiveFGHv not defined

[ericagol]

The latest version of Optim (1.0/1.1) seems to have broken the precompilation in Julia v1.0.0. See lines 3189-3223 of this build:

https://travis-ci.org/github/ericagol/TRAPPIST1_Spitzer/builds/725391351#L3304

The error seems to be triggered by the command "using Optim" in several scripts the above repository.

Yeah that's a duplicate issue. Thanks though.

Thanks! I have tried to use:

Pkg.add(PackageSpec(name="Optim",version="0.22.0"))
Pkg.pin(PackageSpec(name="Optim",version="0.22.0"))

but unfortunately travis continues to upgrade Optim to 1.1.

[pkofod]

What about now? :)

@pkofod I tried changing my Julia version to 1.2, and that solved the problem. Thanks for checking in; greatly appreciated!
