When I tried to install QuantEcon package I have the following messages.

I think this is a compatibility problem but do not know how to fix it.

How can I fix the problem?

I've run into a similar problem installing with BlackBoxOptim.jl on master simultaneously with QuantEcon.jl. It seems like a downstream dependency of QuantEcon has a compat bound on Distributions. So far, I haven't been able to find it yet -- is this a known issue?

Steps to reproduce:

julia> using Pkg
julia> Pkg.activate("TestEnvironment")
julia> Pkg.add("QuantEcon")
julia> Pkg.add(PackageSpec(name="BlackBoxOptim", rev = "master"))

Thanks for your feedback @jacobadenbaum and @SeongDeokKo .

I'm hoping @oyamad or @sglyon will have time to respond. (Also CC @jlperla.)

[jlperla]

Are far as I can tell, the only constraint for a compatability bound here is on DSP? https://github.com/QuantEcon/QuantEcon.jl/blob/master/Project.toml#L26

And it lower bounds it as far as I can tell? (https://pkgdocs.julialang.org/dev/compatibility/ )

But the DSP project it refers to is another animal entirely... This is the current master of the DSP project file: https://github.com/JuliaDSP/DSP.jl/blob/master/Project.toml#L17-L24

That looks like a very stringent set of constraints, so I am not surprised if the resolver can't find a feasible solution.

But I could be missing somethign here.
