Version conflicts between StatsModels and Bootstrap prevents adding StatsKit

[braamvandyk]

Short version: I can't add StatsKit to Julia v1.2 due to version conflicts:

This was apparently resolved (at least according to juliangehring/Bootstrap.jl#52), but apparently hasn't made its way to the current release. Not really a StatsKit.jl issue directly, but that is where the pain is now felt.

Thanks for the report. Unfortunately, as you say, it cannot be fixed in StatsKit. Bootstrap.jl still doesn't support StatsModels 0.6, and it looks like the dependencies resolver is unable to find a working combination of packages (AFAIK it's going to be rewritten to fix this at some point). I've requested a new version at https://github.com/juliangehring/Bootstrap.jl/pull/57#issuecomment-527624993.

It isn't the resolver's fault, it is what Pkg feeds the resolver. Fortunately, we have a fix on the way: https://github.com/JuliaLang/Pkg.jl/pull/1330. Using that PR:

(Pkg) pkg> add StatsModels
 Resolving package versions...
  Updating `~/Pkg.jl/Project.toml`
  [3eaba693] + StatsModels v0.6.3
...

(Pkg) pkg> add Bootstrap
 Resolving package versions...
 Installed StatsModels ─ v0.5.0
 Installed Bootstrap ─── v2.1.0
  Updating `~/Pkg.jl/Project.toml`
  [e28b5b4c] + Bootstrap v2.1.0
  [3eaba693] ↓ StatsModels v0.6.3 ⇒ v0.5.0
...

[KristofferC]

To workaround it with the current Pkg you can do add StatsModels Bootstrap in one call to Pkg.

Will be fixed by https://github.com/JuliaRegistries/General/pull/3230.
