Unable to precompile -- "allequal not defined"

[zornsllama]

When I attempt to add and precompile Flux, I receive the error LoadError: UndefVarError: allequal not defined. This problem persists when creating a new environment and adding just Flux, so it seems it's not just a weird dependency issue? Any help would be greatly appreciated!

[ToucheSir]

Do you have anything in your global environment?

[zornsllama]

Yes, is there any way to pin down what might be causing a conflict?

[darsnack]

Probably due to JuliaDiff/ChainRules.jl#598
The main issue seems to be finding a reliable reproducer.

[mcabbott]

Yes to the CR 598 issue. Unfortunately nobody seems to be able to reproduce this.

If it happens reliably in your setup @zornsllama, try ] dev-ing ChainRules, and check it still happens. Then edit the this line to say @non_differentiable Compat.allequal(::Any). Or perhaps

@static if isdefined(Compat, :allequal)
    @non_differentiable Compat.allequal(::Any)
end

These steps shouldn't harm anything, but it's possible they may avoid whatever is causing this.

EDIT:
I did pkg"up". At first, I got the same error. But now, things seem to work.

[ToucheSir]

Can you confirm that this is not a case of JuliaDiff/ChainRulesCore.jl#553 (comment)?

[KronosTheLate]

I have, as mentioned in the edit, since updated all packages and thing are working now. So I am unable to do further tests without instantiating the same env. And unfortunately, I simply have more pressing things to do right now.
