The following code does not work when called from path that has blank space. using JuMP, AmplNLWriter, Ipopt_jll mod = Model(() -> AmplNLWriter.Optimizer(Ipopt_jll.amplexe)) set_attribute(mod, "output_file", joinpath(@__DIR__,"output.txt")) optimize!(mod) The output is: Ipopt 3.14.17: output_fi…

This is fixed in v1.2.3 of AmplNLWriter.jl. For earlier versions, the work-around needed to be: output_file = joinpath(@__DIR__,"output.txt") set_attribute(mod, "output_file", "\"$(output_file)\"")
