buildPythonPackage fails with "404: Not Found"

[Jean-Paul Calderone]

using mach-nix bdc97ba and pypi-deps-db 347b6270718ed2191078c852329fd32f04dd34ed building buildPythonPackage ... fails:

error: unable to download 'https://github.com/DavHau/nix-pypi-fetcher/tarball/9baa976328fe4fc93d89906f92566a5faeedd1a1': HTTP error 404

       response body:

       404: Not Found
(use '--show-trace' to show detailed location information)

DavHau suggests the mach-nix code generator may need to be updated to reflect the switch to nix-pypi-fetcher-2 in pypi-deps-db

[Adam Griffiths]

This is currently broken in the latest official release (3.5.0), which is specified by the installation instructions on the front-page.

error: unable to download 'https://github.com/DavHau/nix-pypi-fetcher/tarball/8c1b9cef5570d9d9bfef9eb10920ee5aec712b4c': HTTP error 404

It is possible to switch to a newer version in Git, the missing tarball breaks things for existing users.

Example fix for anyone looking:
