I am not able to install PackageCompiler:

This same error recently happened to me with my package. So, what I found was running `update` cleaned up dependency issues that I had no idea were happening. Not saying this is the case here, but it’s an obvious thing to try if you haven’t yet.

A crude workaround (given one is not doing anything special like tracking unregistered dependencies) is to delete the manifest file `~/.julia/environments/v1.3/Manifest.toml` then proceed normally with `(v1.3) pkg> add PackageCompiler`.

Note the `Pkg` resolver in Julia 1.4 has been adjusted to avoid these kinds of errors in the first place.
