It's a 12.04 Ubuntu.

[ionelmc]

Seems the problem is caused by a python-setuptools installed with apt.

[ionelmc]

Actually, it appears to be a spurious error? It fails but then it appears the uninstall worked:

Cannot uninstall requirement setuptools, not installed

Maybe this is still worth checking.

Duplicate of #2438?

[ionelmc]

Definitely related though I wouldn't be surprised if one can be fixed without the other.

[qwcode]

see #2438 (comment)

I also tested your scenario (mentioned in the description) using the latest develop branch of pip, and don't get the failure

PYTHONPATH=pip-6.1.0.dev0-py2.py3-none-any.whl python -mpip uninstall -y setuptools
DEPRECATION: Uninstalling a distutils installed project (setuptools) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.
Uninstalling setuptools-0.6rc11:
  Successfully uninstalled setuptools-0.6rc11`

and afterwards pip list does not show setuptools

BUT, "setuptools" is still importable, but not sure what can be done here, since this version of python-setuptools is using a pure distutils install and pip can't properly uninstall that as mentioned in the deprecation message

in any case, I don't think you should be removing a distro version of setuptools using pip, since it can break things that depend on python-setuptools. Do apt-cache showpkg python-setuptools and you'lll see the distro packages that depend on python-setuptools (see "Reverse Depends")
