Problems with Installation

[CleggTom]

Expected behavior

Installation of the package

Actual behavior

Julia returns an error stating:
unsatisfiable package requirements detected: no feasible version could be found for package: ChunkedArrays

after this package is installed and the BEFW package is installed again it returns the same error as above for the following packages:

Parameters ResettableStacks DataStructures Iterators

After this it finally allows installation.

Steps to reproduce

1.Start with clean install of Julia 0.5.1
2.Run Pkg.add("BioEnergeticFoodWebs")
3.Add the packages that are returned by the error

System information

• julia 0.5.1
• Pkg.status("BioEnergeticFoodWebs") - NA
• OSX 10.10.5

ChunkedArrays are not required by BioEnergeticFoodWebs -- so the problem may be with another package, or one of the dependencies.

When you run Pkg.status("BioEnergeticFoodWebs"), do you see 0.3.0?

[CleggTom]

yep after installing all the packages listed above i now have 0.3.0.

I'm now running into a problem when I load the package telling me it has failed to precompile the StochasticDiffEq module. I assume this is all due to the switching to the new differential equation solver

[tpoisot]

This is actually an issue in StochasticDiffEq: SciML/StochasticDiffEq.jl#16 -- it should be solved soon.

You can temporarily work using 0.2.0 with

Pkg.pin("BioEnergeticFoodWebs", v"0.2.0")

when this will be fixed, just go through

Pkg.free("BioEnergeticFoodWebs")
Pkg.update()

[tpoisot]

@TomClegg94 The issue is in Parameters.jl, and it should be temporarily fixed in a few hours.

[ChrisRackauckas]

This should be fixed now. Sorry for the wait!

[CleggTom]

The package is all working now and i'm on version 0.3.0.

However, in order to get the new version I re-added the package Pkg.add("BioEnergeticFoodWebs") with a clean install of Julia and got the same error as outlined in the first post (Julia wont install BioEnergeticFoodWebs until all those other packages are manually installed)

@TomClegg94 I'm unable to reproduce. How did you install Julia?

[CleggTom]

I used the .dmg on julialang.org. I also use the Juno IDE on atom.

[tpoisot]

OK -- I see nothing in the code here that could trigger this error, and I'm unable to reproduce.

[ChrisRackauckas]

@TomClegg94 can you post your Pkg.status()? Pinned packages can sometimes do this.
