Dear,

I am trying to package swh.model, as reported previously. :-)
Well, I simply run:

  guix import pypi -r swh.model

and then using the wise advises of Marius, everything almost works.

However,

  ./pre-inst-env guix install python-swh-model -p /tmp/swh
  GUIX_PROFILE="/tmp/swh"
  . "$GUIX_PROFILE/etc/profile"

  swh-identify foo

returns this error:

--8<---------------cut here---------------start------------->8---
Traceback (most recent call last):

--8<---------------cut here---------------end--------------->8---

Well, because there is:

--8<---------------cut here---------------start------------->8---
+    (propagated-inputs
+     `(("python-attrs" ,python-attrs)
+       ("python-attrs-strict" ,python-attrs-strict)
--8<---------------cut here---------------end--------------->8---

in the definition of "python-swh-model", I should miss something to
correctly propagate it.  What could it be?


All the best,
simon
