The auto-precompilation that happens after `pkg> add/up` etc. tries to be quieter about package errors because during Pkg operations you may only care about a subset of packages in your environment.

For that reason auto-precompilation does two things:

1. Only warns that packages have errored, and doesn’t show the full stack trace. (That warning comes with guidance to run `precompile` manually, or load the package)
2. Remembers if packages have errored in previous Pkg precompile attempts and skips them, just showing the `1 skipped during auto due to previous errors` type of message.

Explicitly calling `pkg> precompile` retries precompilation on all packages, and will show the full error messages.

And of course packages can just be loaded via `using/import` to hit the classical precompile process and error handling.
