If someone is running a brew python and does "pip install numpy" will pip find a binary wheel that will then not work? That would be bad, but maybe not our problem -- brew users should be using brew to build numpy anyway.
No that is not how homebrew works. Brew does not pack anything that pip installable: https://github.com/Homebrew/homebrew/wiki/Homebrew-and-Python so that would be a big issue. Especially since installing numpy with pip and brew python just works without any problem when building from source.
There are unofficial brew taps (channels) with python packages but this not the recommended way.
OK, then I'll re-phrase:
Brew users should be building from source anyway, even if they use pip to do it.
But it would be bad if they had to go out of their way to do that -- I've lost track of pip's default behavior in this regard.
We should be fine for homebrew. I believe: 1) The wheels work for homebrew as well 2) Homebrew won't pick them up by default at the moment Homebrew python has a more specific architecture version then the python.org python or system python: $ /usr/local/Cellar/python/2.7.6/bin/python -c "import distutils.util; print(distutils.util.get_platform())" macosx-10.9-x86_64 So - for now - pip won't recognize the 10.6_intel wheel as matching the required 10.9_x86_64 suffix on the wheel (can be solved by renaming the file as further up the thread). But - in any case - the wheels work fine in homebrew: mkvirtualenv homebrew-2.7 --python=/usr/local/Cellar/python/2.7.6/bin/python pip install nose # this doesn't see the wheel - because of the platform tag # starts to download and install from source pip install --pre --find-links . numpy # this works pip install numpy-1.8.1rc1-cp27-none-macosx_10_6_intel.whl # tests all pass python -c 'import numpy; numpy.test()' # We're picking up the right numpy python -c 'import numpy; print(numpy.__file__)' deactivate # same for 3.3 mkvirtualenv homebrew-3.3 --python=/usr/local/Cellar/python3/3.3.5/bin/python3 pip install nose python -c 'import numpy' pip install --pre --find-links . numpy pip install numpy-1.8.1rc1-cp33-cp33m-macosx_10_6_intel.whl python -c 'import numpy; numpy.test()' So I think we're good. We should surely set up automated testing to assure ourselves that this is still true, when there's time, it shouldn't take very long. Cheers, Matthew
