Error when trying to install JuMP

General Usage

Hi there

I have a Julia 1.0.1 on a windows machine. When installing JuMP I get the following error

v1.0) pkg> add JuMP

So seemingly ForwardDiff is the problem. update was run before the installation.

Whats the output of pkg> status? Do you have ForwardDiff pinned for example?

The output is

v1.0) pkg> status

Ok, that is weird. I can pkg> add JuMP without a problem with the same package state as you have:

(v1) pkg> st

Can you post the content of C:\Users\Christian\.julia\environments\v1.0\Project.toml and C:\Users\Christian\.julia\environments\v1.0\Manifest.toml to a gist or something?

Manifest.toml
Project.toml
Edit: these are before uninstalling ForwardDiff

Thanks for your patience by the way

Edit:
The following worked:

  • uninstall ForwardDiff
  • install JuMP

But now I’m stuck with ForwardDiff 0.9 instead of 0.10

Thanks. pkg> rm ForwardDiff; add JuMP; add ForwardDiff seems to work. I wonder why Pkg refuses to downgrade ForwardDiff, maybe because it is installed explicitly? @kristoffer.carlsson?

7

Just out of interest: Why does it even try to downgrade ForwardDiff? I don’t need to say that this is not optimal and it should not be necessary (I know of the new package environements that Julia 1.0 has but still…)

8

Because JuMP has that as a requirement: https://github.com/JuliaRegistries/General/blob/996cdd63bdf8de37d4713fe67d96e0ccef21c499/J/JuMP/Compat.toml#L62 for some reason.
