Conda package broken on macOS with python 3.6.3

Issue #154 closed
Malcolm Ramsay created an issue

When installing the freud conda package into a new conda environment with python 3.6.3 which is the default python 3.6 version,

#!bash
$  conda create -n freud -c glotzer freud

the install is fine, but when trying to import freud

#!bash
$ python -c "import freud"
Fatal Python error: PyThreadState_Get: no current thread

zsh: abort           python -c "import freud"

Unusually by installing python 3.6.1

#!bash
$ conda install python=3.6.1

the command which previously failed

#!bash
$ python -c "import freud"

now works fine.

I have also checked using python 3.5, and the 3.5.4 doesn't work, but 3.5.2 does.

I raised an issue in conda-build related to this in that it is not possible to pin the patch version of python as a run or test dependency https://github.com/conda/conda-build/issues/2571.

I have attached the environment.yml file of the failing environment.

    Thanks for reporting this, @malramsay64. We have been working on this issue today. It seems to be caused by library linking to Python that may be avoidable. @joaander is working on a solution. I will update this if/when we release a new conda package that solves the problem.

    Related issue #145.

    Don't link against the python library

    This should fix ABI compatibility issues with freud binary builds and different python minor versions.

    This problem should be solved with the release of v0.6.3. Please upgrade to the latest freud release if this problem occurs.
