I just downloaded Julia Pro and tried to install NLsolve. Here is the issue is shows:
resolve is unable to satisfy package requirements.
The problem was detected when trying to find a feasible version
for package Optim.
However, this only means that package Optim is involved in an
unsatisfiable or difficult dependency relation, and the root of
the problem may be elsewhere.
Optim is installed without any requirement. It is version 0.15.3.
Does anyone know how to make it work?
