Problem in import pygrib

[HeXinsheng16]

I successfully installed pygrib2.0.2 by pip, but when I import it in python, I will met the problem:

>>> import pygrib

Traceback (most recent call last): File "", line 1, in ImportError: dlopen(/Users/xxx/anaconda/lib/python2.7/site-packages/pygrib.so, 2): Library not loaded: @rpath/libmfhdf.0.dylib Referenced from: /Users/xxx/anaconda/lib/libnetcdf.11.dylib Reason: image not found

I tried in python2.7.13, 3.6.1, and the way of installing it I tried pip, conda. But I will always meet this problem. So how to solve the problem?
