Why pip3 install in python2 sitepackages

Question

First I use

Python 3.6.5
Python 2.7.14
and mac.

In my case, I just download module like numpy(for example, and other\'s same)

Answer 1

It seems that pip3 refers to Python-2.7's pip module or any other version of Python-3 that you have installed on your machine. However, you can install packages directly using the intended Python version. You'd need to just use -m option.

python3.6 -m pip install numpy

Another option is to changing the source path that pip3 refers to. You can do this by finding the path of Python-3.6's pip and just bind it to pip3 alias.
