very much for testing.\r\n\r\nSo, what I did was upload new builds of matplotlib with a new \"build tag\" in their name.  The new wheels have names like this:\r\n\r\n```\r\nmatplotlib-2.0.0b3-1-cp35-cp35m-macosx_10_6_intel.macosx_10_9_intel.macosx_10_9_x86_64.macosx_10_10_intel.macosx_10_10_x86_64.whl\r\n```\r\n\r\nwhere `-1-` is the build tag.  It looks like pip is still trying to get the older versions without the build tag.  I've deleted these from pypi just now, and with this:\r\n\r\n```\r\npip install --no-cache-dir --pre matplotlib\r\n```\r\n\r\nI now get the right wheel.   I think the cached pypi listing times out after a while, so this should be the default in due course (without `--no-cache-dir`).    Does this work for you now?"}}
