Cannot install PiecewiseLinearOpt package

I try to install PiecewiseLinearOpt package, but it gets into conflict with other Julia packages. Firstly, it highlighed JuMP:

julia> Pkg.add("PiecewiseLinearOpt")

Following the advice on the topic below, I’ve uninstalled JuMP (although I have version 0.20.0) and tried to install PiecewiseLinearOpt package first, but then it conflicts with other package…

See the aforementioned topic in here:

Is there any safe way to install it instead of removing packages from here and there and installing them back?

I’m working on Windows 10, Julia 1.2.0
