how to shoot yourself in the foot on python3.2

[wm75]

Perhaps unavoidably pip on python3.2 asks you to upgrade to pip version 8.0.0:

You are using pip version 7.1.2, however version 8.0.0 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

What's really stupid is what happens if you follow that advice:

python3.2 -m pip install pip --upgrade
Collecting pip
Downloading pip-8.0.0-py2.py3-none-any.whl (1.2MB)
100% |████████████████████████████████| 1.2MB 663kB/s
Installing collected packages: pip
Found existing installation: pip 7.1.2
Uninstalling pip-7.1.2:
Successfully uninstalled pip-7.1.2
Successfully installed pip-8.0.0

So, ok, nobody cared to check the python version in setup.py and do something to inform the user of the foreseeable problems, but even worse, your way back is barred:

python3.2 -m pip install pip==7.1.2 --upgrade
/usr/local/lib/python3.2/site-packages/pip/_vendor/pkg_resources/init.py:87: UserWarning: Support for Python 3.0-3.2 has been dropped. Future versions will fail here.

So what good is this user warning if the tool fails anyway?
Dropping support for Python3.2 is one thing, but doing so in such an ill-planned way another.

Not sure about this, but would it help to offer the 8.0.0 wheel only as pip-8.0.0-py2.py33-none-any.whl to avoid its use when installing from Python3.2, then add a version check to the source distribution that prevents installation with an appropriate error message?

This one catched me too on Debian with Python3.2 and it's absolutely annoying that the pip package manager recommends to install a version which turns the package manager into an unusable state on the system.

since yesterday, you can at least restore things by running:

curl https://bootstrap.pypa.io/3.2/get-pip.py | python3.2 - --upgrade

(see the new get-pip.py repo at https://github.com/pypa/get-pip)

[simon-clematide]

That's very helpful information. Thanks.

Simply avoiding the upgrade recommendation would already help a lot.
Avoiding the upgrade itself would be even better !

Closing this. Python 3.2 is no longer supported and the data-requires-python support in newer versions of pip won't download a version that doesn't support your current running Python.
