I encountered the following:

I tried to install `PETsc.jl` on Julia-1.0. This triggered an _Unsatisfiable Requirement_ error for one of its dependencies. In an attempt to modify the package as to limit its dependencies to 1.0 compatible packages, I tried:

```julia
dev https://.../PETsc.jl

```

This gives me the same version incompatibility error as before, but does indeed pull in the repo and places it in `dev/`. However, the package is not considered installed and as a consequence `using PETsc` fails.

How do I now force the package manager and loading subsystem to consider this package?

You should probably look into fixing this dependency first. You can probably override the reolver by manually cloning and then `dev` the paths.
