Unsatisfiable requirements when trying to install OMETIFF due to Images.

[kellertuer]

When I try to ] add OMETIFF (because I need that for another project, namely TestImages.jl, I get

ERROR: Unsatisfiable requirements detected for package OMETIFF [2d0ec36b]:

If I read that correctly, julia (running version 1.1 on Mac OS here) requires that OMETIFF to be at least at version 0.2.0, while Images requires that OMETIFF is less than 0.1.1 (fifth line). I could not find OMETIFF.jl in your project.toml so I am not completely sure where this requirement comes from, but can someone check, whether Images is ok with a newer version of OMETIFF.jl to solve this error? Or is it OMETIFF that is wrong here?

My guess this is another one of those cases where automatically-imposed upper bounds are getting in the way (JuliaRegistries/Registrator.jl#122). Check Images' and OMETIFF's Project.toml to see if there are any "real" version restrictions. Then check ~/.julia/registries/General and see about editing the Compat.toml files to fix the bounds. If that's what's needed, then please bundle those changes up as a PR to https:/JuliaRegistries/General.

I already tried that, but OMETIFF does not yet have a Project.toml and the REQUIRE looks okay. In Images there is no direct restriction, so it might come from one of the packages it depends on, but how can I find that out?
Edit: I did find it out. the .julia/registries/General/O/OMETIFF/Compat.toml

had the lines

["0.1.2-0"]
ImageMetadata = "0-0.6"
Images = "0-0.17"
JSON = "0"

when I changed that to

["0.1.2-0"]
ImageMetadata = "0-0.7"
Images = "0-0.18"
JSON = "0"

(since those are the versions I have installed), I was able to install OMETIFF.

I still don't understand what that does, so I also don't know how and where to report that (also see above, the OMETIFF does not yet have a Project.toml.

You did the right thing. Just submit that change to JuliaRegistries. Thanks!

Cool.After working with Julia for a while I am slowly getting into fixing things I notice, that's fun :)

Hey (I'm the author of OMETIFF.jl 👋) thanks for taking care of this! I've just updated it to use the new the Project.toml setup: tlnagy/OMETIFF.jl#34
