Using PyVISA with Python 2.7; Cannot import visa or pyvisa module

I have installed:

NI VISA and
followed the instructions in FAQ for Homebrew:

"My Mac .apps don’t find /usr/local/bin utilities!"

GUI apps on macOS don’t have /usr/local/bin in their PATH by default.
If you’re on Mountain Lion or later, you can fix this by running sudo
launchctl config user path "/usr/local/bin:$PATH" and then rebooting,
as documented in man launchctl. Note that this sets the launchctl PATH
for all users.

Also installed the following:
(pip install ):

pyvisa

pyserial

numpy

I am not sure what I am not doing correctly but I am not able to import visa.py or pyvisa.py.

When I send this code in:

import sys print(sys.path)

sys.path.insert(0,"/home/tranjonathan/Documents/pyvisa-master/build/lib")

import visa

This is what IDLE returns:

['/Users/tranjonathan/Desktop', '/Users/tranjonathan/Documents', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python27.zip', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-old', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload', '/Users/tranjonathan/Library/Python/2.7/lib/python/site-packages', '/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages']

Traceback (most recent call last):
File "/Users/tranjonathan/Desktop/test_script.py", line 7, in
import visa
ImportError: No module named visa

tl;dr

I still have not been able to import visa or pyvisa. Need to control external test equipment using USB/GPIB
