Numpy version >= 1.10 dependency issue.

[Erotemic]

I'm working with a development version of numpy version 1.10.0.dev0-30d755d.

When trying to install matplotlib I get an error saying
error: numpy 1.10.0.dev0-30d755d is installed but numpy>=1.6 is required by set(['matplotlib'])

This is because 1.10 is registering as less than 1.6.

I'm not sure if this is fixed in the head repository, but this causes an issue when using current release on pip. Should be an easy fix. I just wanted to ensure people were aware of it.

I feel this should be a bug against setuptools or pip?

It might be that your setuptools install needs to be updated to properly
handle the new version numbering system.

Normally this kind of thing happens when one uses string comparison to compare versions. However we are using LooseVersion in setupext.py which should work correctly.

I cannot reproduce this with numpy 1.10.0.dev0+49617ac and matplotlib master
Python 3.4.3 setuptools 18.0.1 pip 7.1.0

looseVersion is from distutils so it should be independent of setuptools/pip version unless setuptools does something funny

And additionally, I don't think this error message even comes from matplotlib -- it's coming from pip.

I am now getting this too, but I think I have 1.9.2 installed via conda.

Because I am feeling cranky, I assume this is fallout from merging #4668

[tacaswell]

although, both python setup.py develop and python setup.py install work for me, python setup.py test does not

[tacaswell]

I had a rouge install of numpy which 'pip remove numpy` fixed.

Closing as it is either a) a local configuration issue or b) bug in upstream tooling.
