Can’t reproduce this, so you’ll need to give us a bit more context.

Thank You, Nils.  
Where can I see the versionsinfo() of Primes? Is no loaded…

`versioninfo()` is a command to enter at the Julia REPL which will provide information about your Julia installation and system.

Yes, and the problem is surely not about Primes.jl, but rather your default package environment. You can see that with `using Pkg; Pkg.status()`.

Thank you very much for your efforts.
