Mac os fatal error: 'numpy/arrayobject.h' file not found

$ python setup.py install 出错信息如：

clang -fno-strict-aliasing -fno-common -dynamic -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I/usr/local/include -I/usr/local/opt/openssl/include -I/usr/local/opt/sqlite/include -I/usr/local/Cellar/python/2.7.10_2/Frameworks/Python.framework/Versions/2.7/include/python2.7 -c hmmlearn/_hmmc.c -o build/temp.macosx-10.10-x86_64-2.7/hmmlearn/_hmmc.o -O3
hmmlearn/_hmmc.c:239:10: fatal error: 'numpy/arrayobject.h' file not found
#include "numpy/arrayobject.h"
         ^
1 error generated.
error: command 'clang' failed with exit status 

查看numpy路径：

>>> import numpy as np
>>> np.get_include()
输出如：
'/usr/local/lib/python2.7/site-packages/numpy/core/include'

添加NumPy headers 给 CFLAGS:

export CFLAGS="-I /usr/local/lib/python2.7/site-packages/numpy/core/include $CFLAGS"

再次执行，done!
