We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Invalid `dev` version identifiers in `setup.py`
There is a bunch of ~invalid~ version matchers (edit: valid, but not parsed correctly by distlib) in `setup.py`.  [PEP 440](https://peps.python.org/pep-0440/) states:

> The canonical public version identifiers MUST comply with the following scheme:
> `[N!]N(.N)*[{a|b|rc}N][.postN][.devN]`

So you are missing a dot and a number in every version identifier that contains the string `dev`.

It is also considered bad practice to have an upper bound on package versions and installers like pip do not typically consider development versions in any case (unless explicitly told to).

See: https://github.com/googleapis/google-api-python-client/issues/2151
