Subject: recursive pypi importer prints backtrace when package does not exist
Date: Sat, 05 Mar 2022 11:46:00 +0100

The recursive pypi importer prints a backtrace when a package does not exist:

--8<---------------cut here---------------start------------->8---
./pre-inst-env guix import pypi -r doesnotexist
following redirection to `https://pypi.org/pypi/doesnotexist/json/'...
Backtrace:

The non-recursive importer does a better job here:

--8<---------------cut here---------------start------------->8---
./pre-inst-env guix import pypi doesnotexist
following redirection to `https://pypi.org/pypi/doesnotexist/json/'...
guix import: error: failed to download meta-data for package 'doesnotexist'
--8<---------------cut here---------------end--------------->8---

This seems to be a duplicate of <https://issues.guix.gnu.org/44115>
and would be fixed by <https://issues.guix.gnu.org/45984>.
