I downloaded Baron (and Pkg.add(“BARON”)) and did a Pkg.update() this morning and since doing that, I’m unable to use JuMP. Does anyone know what might be going on?

Julia Version: Version 0.6.2 (2017-12-13 18:08 UTC)

Update: The problem is clearly with BARON.jl. Removing the package resolved the issue. Sad that I can’t use BARON.jl though ☹ I posted an issue on the github page.

Try `Pkg.checkout("BARON")`. Looks like they did the updates for 0.6 but never tagged the release.

Unfortunately, it looks like even the master branch of BARON.jl still does not support Julia v0.6: [https://github.com/joehuchette/BARON.jl/blob/7e329be8b26ba95e23addc0af07b4b4d4d2c618c/REQUIRE](https://github.com/joehuchette/BARON.jl/blob/7e329be8b26ba95e23addc0af07b4b4d4d2c618c/REQUIRE)

Thanks for looking into this!

The code base is pretty tiny, it would probably be quite easy to update it simply by going through the warnings and errors one at a time.

Yup, totally agree. Unfortunately, actually testing it would require a Baron license, which is harder to come by.
