I frequently get the following error with packages that I’m developing. I usually manage to resolve it but without any understanding or repeatability. How do I tell julia about versions for a package? Am I supposed to tag it in git or some such? I also didn’t see anything about this in the package manager documentation.

Resolving package versions…

Models is an unregistered package that is a dependency of some other package, right? Right now, you need to add that package first, before you add HMM.

Thank you! That worked perfectly and explains it.

By the way, could we add a discourse category for the package manager?

Has anything changed here? For unregistered packages that depend on other unregistered packages, do they need to be added manually in order?

The work to track is [https://github.com/JuliaLang/Pkg.jl/pull/1628](https://github.com/JuliaLang/Pkg.jl/pull/1628) which aims to significantly improve this.

I am getting the same error in my case Xnumber is a dependency of SHbundle and both of them are unregistered.

```julia
ERROR: Unsatisfiable requirements detected for package Xnumber [fdc6275c]:
 Xnumber [fdc6275c] log:
 ├─Xnumber [fdc6275c] has no known versions!
 └─restricted to versions * by SHbundle [685399a2] — no versions left
   └─SHbundle [685399a2] log:
     ├─possible versions are: 0.1.0 or uninstalled
     └─SHbundle [685399a2] is fixed to version 0.1.0

```

Also I have added Xnumber to SHbundle but when i run the following command in gitlab-ci i get the above error.

```julia
- |
      julia --project=docs -e '
        using Pkg
        Pkg.Registry.update()
        Pkg.develop(PackageSpec(path=pwd()))
        Pkg.instantiate()
        using Documenter: doctest
        using SHbundle
        doctest(SHbundle)
        include("docs/make.jl")'

```

I don’t know how much the first answer is relevant to my case as could not understand the solution.
