I’d like to understand better the registry system, and how to troubleshoot this error
ERROR: Unsatisfiable requirements detected for package <<>>
I wanted to use the newest version of SpecialFunctions.jl. The only serious change AFAIK is the addition of spherical bessel functions (why I want to update). However, it seems to be conflicting with a package called ColorVectorSpace, which demands(!) SpecialFunctions v.10. This get’s used by Makie. Also Optim (get’s used by Gadfly). If I want spherical bessels, then I can’t plot! You get the idea.
(@v1.4) pkg> add Gadfly

etc.
So
1.) how do these packages (Optim and ColorVectorSpace) “know” that they can’t use a higher version of SpecialFunctions?
2.) is there really a dependency issue, and how do I help resolve it if there is and
3.) If there is no REAL dependency issue how do I tell them to sit down and shut up?
