Hi zimoun,

That’s because ‘emacs-helm’ depends on ‘emacs-minimal’, not ‘emacs’:

--8<---------------cut here---------------start------------->8---
$ guix graph --path -t bag emacs-helm emacs
guix graph: error: no path from 'emacs-helm <at> 3.6.5' to 'emacs <at> 27.1'
$ guix graph --path -t bag emacs-helm emacs-minimal 
emacs-helm <at> 3.6.5
emacs-minimal <at> 27.1
--8<---------------cut here---------------end--------------->8---

Does it work for you if you do ‘--with-input=emacs-minimal=emacs-next’?

HTH,
Ludo’.
