I’ve found the following behavior that seems to me to be a bug; from a fresh build of master with nothing installed, I install ForwardDiff:
(v0.7) pkg> add ForwardDiff Cloning default registries into /home/sean/.julia/registries Cloning registry Uncurated from "https://github.com/JuliaRegistries/Uncurated.git" ... Installed StaticArrays ───────── v0.8.0 ... [90137ffa] + StaticArrays v0.8.0 ... julia> Pkg.installed()["StaticArrays"] v"0.8.0"
Now if I do
using StaticArrays, the package is not found - I assume this is a deliberate design decision and not a bug, although I’m not sure I agree. However, my next thought is to install it so I can use it - surely this should be a simple operation since the package is already on my system as a dependency of ForwardDiff. Nope:
(v0.7) pkg> add StaticArrays Updating registry at `~/.julia/registries/Uncurated` Updating git-repo `https://github.com/JuliaRegistries/Uncurated.git` Resolving package versions... ERROR: Unsatisfiable requirements detected for package (unknown) [10745b16]: (unknown) [10745b16] log: ├─(unknown) [10745b16] has no known versions! └─found to have no compatible versions left with StaticArrays [90137ffa] └─StaticArrays [90137ffa] log: ├─possible versions are: [0.0.1-0.0.11, 0.1.0-0.1.5, 0.2.0-0.2.1, 0.3.0-0.3.1, 0.4.0, 0.5.0-0.5.1, 0.6.0-0.6.6, 0.7.0-0.7.2, 0.8.0] or uninstalled └─restricted to versions 0.8.0 by an explicit requirement, leaving only versions 0.8.0
I’m not sure I understand what’s going on here, but surely this shouldn’t be the way the system works - after all, I just installed StaticArrays as a dependency, so this should be a no-op. Am I just confused?
I should note that if I first install StaticArrays and then ForwardDiff, everything works as I’d expect.
