Question regarding pip

Every time I write: pip install module (a module from python packages) in the IDLE, I receive a syntax error. should I use 'pip install module' in the IDLE or in the terminal. I use a mac.

pip install module should be run on the shell command line prompt. You will get a syntax error trying to run pip as a python command in the interpretor.

Hi Chris. Please how can I install numpy. I have python 3.4 installed. Whenever I run this command in my Terminal: pip install numpy. I get this :

Rabihs-MacBook-Air:~ rab$ pip install numpy Requirement already satisfied (use --upgrade to upgrade): numpy in /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python Rabihs-MacBook-Air:~ rab$

but when I import numpy in Python 3.4 , I get an error. It seems MAC OS comes with an embedded Python 2.7 with numpy already installed. How can I transfer numpy to Python 3.4

If you're on a system with Python 2.x as the system default, but also have Python 3.x installed, you need to run pip3 to get the Python 3 version of pip to install into the Python 3 site-packages area. Can you try:

pip3 install numpy
