bug#39297: guix repl loads Guild 3.0.0 despite dependency is guile@2.2.6

[Moritz Lell]

When I invoke `guix repl`, I get:

despite `guix show guix` shows a dependency of `guile@2.2.6`

This is incorrect, is it?

That’s perfectly correct: the ‘guix repl’ command comes from the ‘guix’
that you obtained via ‘guix pull’, and which just switched to Guile 3.0
(‘guix pull --news’ should contain an entry about it, but see also
<https://guix.gnu.org/blog/2020/guile-3-and-guix/>.)

Conversely, the ‘guix’ package is still using Guile 2.2, as you saw with
“guix show guix”.  It will switch to 3.0 soonish.

The transition should be mostly complete within a few days so the
situation should be clearer.

HTH!

Ludo’.
