How to find out if precompilation during Pkg.add was successful?

General Usage
,
1

Assume some Julia code adds a package pkg via Pkg.add(pkg). How can subsequent code determine if the package precompiled successfully?

2

If precompilation did not succeed, then there will be an error when trying to use import or using.

Well, is there a way without using import or using (without restarting Julia)? The problem is that you cannot undo such a command. For example, the following leads to an error:

using Pkg
Pkg.activate(; temp = true)
Pkg.add("AxisKeys")
import AxisKeys
Pkg.activate(; temp = true)
Pkg.add("FFTViews")
import FFTViews

It gives

┌ Error: Error during loading of extension AbstractFFTsExt of NamedDims, use `Base.retry_load_extensions()` to retry.
│   exception =

Without the first import it works fine.
