As of just a few days ago, I cannot update or install packages. Here’s a sample of what happens when I try and install Ipopt (note, this is the same error I receive when issuing Pkg.update() as well):

julia\> Pkg.add(“Ipopt”)  
ERROR: resolve is unable to satisfy package requirements.  
The problem was detected when trying to find a feasible version  
for package Compat.  
However, this only means that package Compat is involved in an  
unsatisfiable or difficult dependency relation, and the root of  
the problem may be elsewhere.

Thanks a lot for sharing!

Removing the version number from “Compat” in the “REQUIRE” file and running Pkg.resolve(), resolved it 🙂
