Version 8.0.2 but warning about use of version 7.1.2

[Amorymeltzer]

Not really sure what to make of this. OSX 10.9, pip installed via macports

pip is /opt/local/bin/pip

You are using pip version 7.1.2, however version 8.0.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Output is the same when called via python -m pip. #3433 feels related but is above my paygrade.

What does python -c "from pip.utils import get_installed_version;print(get_installed_version('pip'))" return ?

[Amorymeltzer]

7.1.2, and for good measure:

So basically, you were using pip 8.0.2 in an environment where pip 7.1.2 is installed ?
I'm not sure we want to support such use cases...

[Amorymeltzer]

Well, okay, but then I'm rather confused on how to proceed. pip install --upgrade pip fails with

What does python -c "from pkg_resources import Environment;print(Environment()['pip'])" return ?

[Amorymeltzer]

So you have both 8.0.2 and 7.1.2 installed in the same directory? That's broken. I can't say how it happened, but it's definitely not something we'd support.

[Amorymeltzer]

Good enough for me, thanks! 👍

[pfmoore]

Cool. If you want to fix things up, you're probably best removing both versions of pip from that directory (you'll probably have to do that by hand) and reinstall with something like get-pip.py.

[corwin-of-amber]

Sorry for bumping, but for the sake of future generations, how does one manually remove the offending versions of pip?

[Ivoz]

Find the site-packages folder of that python ( pip show -f pip should help you) and remove the offending directories. pip show -f pip should also tell you the location of all files needed to completely remove it. Sometimes you may also want to remove offending installed executable scripts if they're pointing to a version that you don't want.
