MultiModalMuSig can be installed using old Pkg, but not the new (v1.1+) Pkg

[WuyangFF95]

Dear @funnell , I think that Julia has made a significant change on the package manager Pkg. After Julia 1, it has two versions of Pkg.

The new Pkg (https://docs.julialang.org/en/v1/stdlib/Pkg/#Pkg-1), invoked by pressing "]" in Julia interactive session, cannot install MultiModalMuSig at all.
(v1.1) pkg> add MultiModalMuSig

But if I use the old Syntax of Pkg, I can install MultiModalMuSig.

julia> import Pkg
julia> Pkg.add("MultiModalMuSig")

I think what (v1.1)Pkg does is to create separate environments (in new Pkg they call it "project") just like Anaconda does. Within each project it has different version of packages, and I can safely install different versions of packages without facing with the "dependency hell" issue.

The old Pkg manager cannot install packages into separate project.

But since I'm a beginner for Julia and I just want to use your package, introducing different environment may be too complicated. So I'll close the issue for now.

Hi @WuyangFF95, I'm sorry that you are having difficulties with the installation! The new Pkg should have a default environment that you can install packages to, so it should work similar to the old way.

This part I think is odd because I can't think why it would be looking in this directory.

When you install the package it should look something like this:

(v1.1) pkg> add MultiModalMuSig
