Users on Python 3.7 only find unusable `dev1` version and can't update

[torsava]

Hi,
ferrypick installed (--user) from PyPI doesn't work. It fails with:

$ ferrypick --help
Traceback (most recent call last):
  File "/home/torsava/.local/bin/ferrypick", line 5, in <module>
    from ferrypick import main
ModuleNotFoundError: No module named 'ferrypick'

Steps to reproduce:

$ pip install --user ferrypick
$ ferrypick --help

It seems the module actually isn't there. When uninstalling ferrypick, only the binary and dist-info are listed:

$ pip uninstall ferrypick
Found existing installation: ferrypick 0.1.dev1
Uninstalling ferrypick-0.1.dev1:
  Would remove:
    /home/torsava/.local/bin/ferrypick
    /home/torsava/.local/lib/python3.7/site-packages/ferrypick-0.1.dev1.dist-info/*
Proceed (y/n)?

This was supposed to be fixed in dev2. You have dev1 installed. Can you reproduce if you upgrade the package?

The fixer was 1eb8b64

For some reason I am not able to install that version:

$ pip install --user ferrypick==0.1.dev2
ERROR: Could not find a version that satisfies the requirement ferrypick==0.1.dev2 (from versions: 0.1.dev1)
ERROR: No matching distribution found for ferrypick==0.1.dev2

I tripple checked the version, being a dyslexic, but can't find any issue.

It is available on PyPI website, so I'm stumped: https://pypi.org/project/ferrypick/0.1.dev2/#history

[torsava]

Oooh, got it. I'm using Python 3.7 and the dev2 version is labeled as Python 3.8 or higher.

[torsava]

The first one isn't though, so it installed and refused to update.

[torsava]

dev2 version works. I'm renaming the issue to address the left over unusable dev1 version.

[hroncok]

The code is 3.7 incompatible. The packaging issues made it possible to install dev1 on 3.7, but without the actual code. The only way I can think of to fix this is to remove dev1 from PyPI.

I would say that's a good idea.

We can either yank or delete it, I'll figure out what is more appropriate https://twitter.com/di_codes/status/1253166894158417926

[hroncok]

I figure we should yank it. Yank is reversible, so I've done it now.

That is bad either way :/
