To continue with Maurits' use-case, in order to get /exactly/ 1.3, '===' is the
operator to use? Or are we still
discussing that? Personally, I think
pip install yourthing is 1.3
Currently the === operator will give you that, but it’s not really designed for
that. It’s designed as an escape hatch for versions we can’t parse. An example
of where this matters is that ==1.3 will match version 1.3.0, but ===1.3 will
not. So if we want something better than that for “give me exactly 1.3 without
any patches” then that’s under discussion.
Current pip 1.5.6 does not recognize the === operator and gives a
ValueError. That is expected.
pip dev does recognize it, but I do not see the behaviour you say. Let
me try from scratch:
$ virtualenv-2.7 venv-newest
$ cd venv-newest
$ . bin/activate
$ pip install -U setuptools # gets 8.0.4
$ pip install https://github.com/pypa/pip/tarball/develop#egg=pip-dev
$ pip install -U --trusted-host pypi.zestsoftware.nl -f
