ERROR: UndefVarError: Rmath not defined

[reworkhow]

Got this error with rand(Chisq(2)) after Pkg.update() today.

I guess this is because StatsFun.jl committed "Use the Rmath package since libRmath is gone in 0.5 (#10)" one day ago.

[ararslan]

Yes, that change broke all existing versions of Distributions. Once #512 is merged I'll tag a new release which should fix this. I'm hoping to get all of that done ASAP today. Sorry for the inconvenience!

The temporary solution is Pkg.add("StatsFuns", v"0.2.2", v"0.3.0")

[ararslan]

Actually, you should be now be able to run Pkg.update() and it should work as expected.

[tpoisot]

Didn't saw it got downgraded.

[ararslan]

Yes, StatsFuns v0.3.0 has been temporarily set to Julia 0.5 only.

I'm still getting

ERROR: LoadError: ArgumentError: Rmath not found in path

when I run Pkg.update() I get INFO: No packages to install, update or remove.

EDIT: I had to manually add Rmath.jl for some reason (i.e. Pkg.add("Rmath") did the trick)

[ararslan]

What version of Julia are you on, 0.4? Distributions will have a new tag soon, and once that's available then hopefully this will all be fixed after another Pkg.update().

[bdeonovic]

Thanks for the comment, I just had to add Rmath manually, not sure why the Pkg updator wasn't forcing the add.

[ararslan]

Probably because you have StatsFuns 0.2.2, and Rmath is only required by StatsFuns 0.3.0. That'd be my guess, anyway.

[bdeonovic]

Well clearly something needed to require it.
