Good day.
I need to use besselk function from SpecialFunctions package. Unfortunately, SpecialFunctions don’t work under v1.0 Julia version.
At the same time Distributions.jl uses besselk function and work under v1.0
Would somebody help me, how I can use besselk function?
Thank you.

Are you for sure using the package [https://github.com/JuliaMath/SpecialFunctions.jl](https://github.com/JuliaMath/SpecialFunctions.jl)? If I recall what it had was included in Julia but is now a package.
I see it has besselk and is tested to up to 1.1 at least.

Can you please be more precise and give more context? What package did you install? What exact error do you get, if any?

I run Pkg.add(“SpecialFunctions”)
and there is error Unsatisfiable requirements detected for package DebuggerFramework [67417a49]:
