It stems from the fact that Guix doesn=E2=80=99t know about the relation between =E2=80=98python-reques= ts=E2=80=99 and =E2=80=98python=E2=80=99. Even if it did, it=E2=80=99s not clear to me that automatically installing = both would be a good idea. There are cases where one may want to choose a particular variant of the =E2=80=98python=E2=80=99 package rather than have= an arbitrarily chosen default.

Most likely one would provide a file that can be passed to =E2=80=98guix environment -l=E2=80=99 instead of writing down the instructions. :-) Thanks, Ludo=E2=80=99.
