How to install scipy with pip3? - python-3.x

Question

I got the following error when I try to install scipy with pip3 on Mac OS X 10.14.1. Does anybody know what the problem is? I was able to install scipy with pip2.
$ pip3 install scipy

ImportError:
Importing the multiarray numpy extension module failed. Most
likely you are trying to import a failed build of numpy.
If you're working with a numpy git repo, try `git clean -xdf` (removes all
files not under version control). Otherwise reinstall numpy.
