OSX installing numpy via brew for python3

Question

I can't install numpy for python3 via brew.

I type:

brew install numpy --with-python3

then it's OK for python2

Python 2.7.6 (default, Sep  9 2014, 15:04:36) 
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.39)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
>>>

but still not found for python3

Python 3.4.0 (v3.4.0:04f714765c13, Mar 15 2014, 23:02:41) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named 'numpy'
>>>

The correct way to install it is via:

pip3 install numpy

Obviously, you need to install python3 and pip first. I tested and works without any problem.

thanks, I know pip3 works just fine. Maybe I wasn't precise, I need to install from brew. It's about specific version and other dependencies.

The problem with the Homebrew is that it sees only the system's python and the one it installed itself. So you have to first install python3 via brew and then use the --with-python3 option.
