`example' package cannot be installed from a `nar' archive without network access.

[Pierre-Henry Fröhring]

Hello Guix Help List,

I according to :

  https://guix.gnu.org/manual/en/html_node/Invoking-guix-archive.html

It is expected that a `nar' archive is self contained.

--recursive

  When combined with --export, this instructs guix archive to include 
dependencies of
  the given items in the archive. Thus, the resulting archive is 
self-contained: it
  contains the closure of the exported store items.

But I cannot get it to work.
You can find below steps that I use to reproduce the unexpected behaviour.
How to make it work ?

Thank you,
phf
