(A friend asks):
I have a task that I think the MixedModels package may be better able to handle than lme4 in R.
I did a clean Julia install before proceeding to install MixedModels. Unfortunately the current version of NLopt seems broken.
julia> using NLopt INFO: Precompiling module NLopt. ERROR: LoadError: NLopt not properly installed. Please run Pkg.build("NLopt") Pkg.build("NLopt") returns ====================================[ ERROR: NLopt ]===================================== LoadError: SystemError: unable to read directory /Users/johnm1/.julia/v0.5/Homebrew/deps/usr/Library/Taps/staticfloat/homebrew-juliatranslated: No such file or directory while loading /Users/johnm1/.julia/v0.5/NLopt/deps/build.jl, in expression starting on line 54 ========================================================================================= The web page http://pkg.julialang.org/detail/NLopt.html says: Julia v0.5 2016-12-09 to 2017-02-07, v0.3.3, Tests fail. 2016-08-27 to 2016-12-06, v0.3.3, Tests pass. 2016-05-24 to 2016-08-26, v0.3.2, Tests pass. . . .
I did try using Pkg.pin(“NLopt”,v"0.3.2") to downgrade to an earlier version, but still NLopt would not load.
Can you kindly provide guidance on where to go next.
