(The original title was Upgrade pip in virtualenv, but since now I know what the problem is, it makes more sense to rename it to Upgrade pip in virtualenv, when using devpi)
Similar to this question, but the answer given there does not work. I am running a 2.7 virtualenv. I have just been informed:
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.
Ok, let's do that:
» pip install --upgrade pip
Requirement already up-to-date: pip in ./venv2.7/lib/python2.7/site-packages
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.
» pip --version
pip 7.1.2 from /foo/bar/venv2.7/local/lib/python2.7/site-packages (python 2.7)
Uh? Ok, maybe this:
» python -m pip install --upgrade pip
Requirement already up-to-date: pip in ./venv2.7/lib/python2.7/site-packages
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.
» pip --version
pip 7.1.2 from /foo/bar/venv2.7/local/lib/python2.7/site-packages (python 2.7)
No luck. How can I upgrade pip itself?
EDIT
As suggested by @J.J.Hakala:
» pip install --upgrade pip==8.0.0
Collecting pip==8.0.0
Could not find a version that satisfies the requirement pip==8.0.0 (from versions: 0.2, 0.2.1, 0.3, 0.3.1, 0.4, 0.5, 0.5.1, 0.6, 0.6.1, 0.6.2, 0.6.3, 0.7, 0.7.1, 0.7.2, 0.8, 0.8.1, 0.8.2, 0.8.3, 1.0, 1.0.1, 1.0.2, 1.1, 1.2, 1.2.1, 1.3, 1.3.1, 1.4, 1.4.1, 1.5, 1.5.1, 1.5.2, 1.5.3, 1.5.4, 1.5.5, 1.5.6, 6.0, 6.0.1, 6.0.2, 6.0.3, 6.0.4, 6.0.5, 6.0.6, 6.0.7, 6.0.8, 6.1.0, 6.1.1, 7.0.0, 7.0.1, 7.0.2, 7.0.3, 7.1.0, 7.1.1, 7.1.2)
No matching distribution found for pip==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.
So it seems that there is indeed a problem with pypi? On the one hand version 8.0.0 is advertised, on the other hand it can not be found ...
For what it's worth, I am using devpi, which up to now has not given me any trouble ...
EDIT2
Disabling devpi (in ~/.pip/pip.conf) solves the problem. No idea what the root problem is. I have added an issue.
