Installing `master` branch of Circuitscape fails

I'm trying to re-install the development branch of Circuitscape (because I'm having this issue again). julia> Pkg.add(PackageSpec(name="Circuitscape", rev = "master")) Updating git-repohttps://github.com/Circuitscape/Circuitscape.jl.git` Resolving package versions... ┌ Warning: julia version requirement for package Circuitscape not satisfied └ @ Pkg.Operations /Users/sabae/buildbot/worker/package_macos64/build/usr/share/julia/stdlib/v1.2/Pkg/src/Operations.jl:225 ERROR: Unsatisfiable requirements detected for package GDAL [add2ef01]: GDAL [add2ef01] log: ├─possible versions are: [0.1.0-0.1.2, 0.2.0, 1.0.0-1.0.2, 1.1.0-1.1.3] or uninstalled ├─restricted to versions 1.0.1 by an explicit requirement, leaving only versions 1.0.1 └─restricted by compatibility requirements with ArchGDAL [c9ce4bd3] to versions: 1.1.1-1.1.3 — no versions left └─ArchGDAL [c9ce4bd3] log: ├─possible versions are: [0.1.0, 0.2.0-0.2.2, 0.3.0-0.3.3, 0.4.0-0.4.1] or uninstalled └─restricted to versions 0.4.0-0.4 by Circuitscape [2b7a1792], leaving only versions 0.4.0-0.4.1 └─Circuitscape [2b7a1792] log: ├─possible versions are: 5.6.0 or uninstalled └─Circuitscape [2b7a1792] is fixed to version 5.6.0 Stacktrace: [1] #propagate_constraints!#61(::Bool, ::typeof(Pkg.GraphType.propagate_constraints!), ::Pkg.GraphType.Graph, ::Set{Int64}) at /Users/sabae/buildbot/worker/package_macos64/build/usr/share/julia/stdlib/v1.2/Pkg/src/GraphType.jl:1007 [2] propagate_constraints! at /Users/sabae/buildbot/worker/package_macos64/build/usr/share/julia/stdlib/v1.2/Pkg/src/GraphType.jl:948 [inlined] [3] #simplify_graph!#121(::Bool, ::typeof(Pkg.GraphType.simplify_graph!), ::Pkg.GraphType.Graph, ::Set{Int64}) at /Users/sabae/buildbot/worker/package_macos64/build/usr/share/julia/stdlib/v1.2/Pkg/src/GraphType.jl:1462 [4] simplify_graph! at /Users/sabae/buildbot/worker/package_macos64/build/usr/share/julia/stdlib/v1.2/Pkg/src/GraphType.jl:1462 [inlined] (repeats 2 times) [5] resolve_versions!(::Pkg.Types.Context, ::Array{Pkg.Types.PackageSpec,1}) at /Users/sabae/buildbot/worker/package_macos64/build/usr/share/julia/stdlib/v1.2/Pkg/src/Operations.jl:317 [6] #add#100(::Bool, ::typeof(Pkg.Operations.add), ::Pkg.Types.Context, ::Array{Pkg.Types.PackageSpec,1}, ::Array{Base.UUID,1}) at /Users/sabae/buildbot/worker/package_macos64/build/usr/share/julia/stdlib/v1.2/Pkg/src/Operations.jl:962 [7] #add at ./none:0 [inlined] [8] #add#25(::Bool, ::Base.Iterators.Pairs{Union{},Union{},Tuple{},NamedTuple{(),Tuple{}}}, ::typeof(Pkg.API.add), ::Pkg.Types.Context, ::Array{Pkg.Types.PackageSpec,1}) at /Users/sabae/buildbot/worker/package_macos64/build/usr/share/julia/stdlib/v1.2/Pkg/src/API.jl:99 [9] add at /Users/sabae/buildbot/worker/package_macos64/build/usr/share/julia/stdlib/v1.2/Pkg/src/API.jl:69 [inlined] [10] #add#24 at /Users/sabae/buildbot/worker/package_macos64/build/usr/share/julia/stdlib/v1.2/Pkg/src/API.jl:67 [inlined] [11] add at /Users/sabae/buildbot/worker/package_macos64/build/usr/share/julia/stdlib/v1.2/Pkg/src/API.jl:67 [inlined] [12] #add#20 at /Users/sabae/buildbot/worker/package_macos64/build/usr/share/julia/stdlib/v1.2/Pkg/src/API.jl:64 [inlined] [13] add(::Pkg.Types.PackageSpec) at /Users/sabae/buildbot/worker/package_macos64/build/usr/share/julia/stdlib/v1.2/Pkg/src/API.jl:64

Trying to update ArchGDAL yields roughly the same error (suggesting that existing gdal library isn't acceptable). I recently updated all of my R geospatial libraries and so am wondering if I've moved "too far" forward. Or is this error telling me something else is wrong?

Updating to Julia 1.4 seems to solve this error.

Ah, yep, Circuitscape requires Julia 1.4 or higher at this time. Glad it was sorted!
