Don't refer to non-existent get-pip versions

solarkraft commented 2 years ago

I've lately been messing around with Python 3.1, trying to get PIP. The installation script errors out with

ERROR: This script does not work on Python 3.1 The minimum supported Python version is 3.7. Please use https://bootstrap.pypa.io/pip/3.1/get-pip.py instead.

So naturally I tried to find get-pip for Python 3.1, considering that I've just been told that it exists.

Thankfully this lie was eventually cleared up:

We've never had a get-pip.py for Python 3.1.

It turns out that this code only takes the current version of Python you're running and generates a get-pip link for it.

if this_python < min_version:
    message_parts = [
        "This script does not work on Python {{}}.{{}}".format(*this_python),
        "The minimum supported Python version is {{}}.{{}}.".format(*min_version),
        "Please use https://bootstrap.pypa.io/pip/{{}}.{{}}/get-pip.py instead.".format(*this_python),
    ]
    print("ERROR: " + " ".join(message_parts))

It would probably better be changed to avoid unnecessarily confusing users by pointing at get-pip versions that don't exist.
