Pip Install not installing into correct directory?

Question

I can't seem to use sudo pip install correctly so that it installs into the following directory:

/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/ 

so that I can then import the module using python

I've run

sudo pip install scikit-learn --upgrade 

Result

Requirement already up-to-date: scikit-learn in /usr/local/lib/python2.7/site-packages Cleaning up... 

However, it's not in the correct directory

How do I get sudo pip install to install into correct directory?

In addition, I've tried

sudo pip install Scrappy

I get the following message

new-host-2:site-packages Chris$ sudo pip install Scrapy Password: Requirement already satisfied (use --upgrade to upgrade): Scrapy in /usr/local/lib/python2.7/site-packages Requirement already satisfied (use --upgrade to upgrade): Twisted>=10.0.0 in /usr/local/lib/python2.7/site-packages (from Scrapy) Requirement already satisfied (use --upgrade to upgrade): w3lib>=1.8.0 in /usr/local/lib/python2.7/site-packages (from Scrapy) Requirement already satisfied (use --upgrade to upgrade): queuelib in /usr/local/lib/python2.7/site-packages (from Scrapy) Requirement already satisfied (use --upgrade to upgrade): lxml in /usr/local/lib/python2.7/site-packages (from Scrapy) Requirement already satisfied (use --upgrade to upgrade): pyOpenSSL in /usr/local/lib/python2.7/site-packages (from Scrapy) Requirement already satisfied (use --upgrade to upgrade): cssselect>=0.9 in /usr/local/lib/python2.7/site-packages (from Scrapy) Requirement already satisfied (use --upgrade to upgrade): six>=1.5.2 in /usr/local/lib/python2.7/site-packages (from Scrapy) Requirement already satisfied (use --upgrade to upgrade): zope.interface>=3.6.0 in /usr/local/lib/python2.7/site-packages (from Twisted>=10.0.0->Scrapy) Requirement already satisfied (use --upgrade to upgrade): cryptography>=0.2.1 in /usr/local/lib/python2.7/site-packages (from pyOpenSSL->Scrapy) Requirement already satisfied (use --upgrade to upgrade): setuptools in /usr/local/lib/python2.7/site-packages (from zope.interface>=3.6.0->Twisted>=10.0.0->Scrapy) Requirement already satisfied (use --upgrade to upgrade): cffi>=0.8 in /usr/local/lib/python2.7/site-packages (from cryptography>=0.2.1->pyOpenSSL->Scrapy) Requirement already satisfied (use --upgrade to upgrade): pycparser in /usr/local/lib/python2.7/site-packages (from cffi>=0.8->cryptography>=0.2.1->pyOpenSSL->Scrapy) 

Both these instances demonstrate that it's been installed but not correctly. For example, when I run the following import in python:

import scrapy --------------------------------------------------------------------------- ImportError                               Traceback (most recent call last) <ipython-input-6-51c73a18167b> in <module>() ----> 1 import scrapy  ImportError: No module named scrapy 

I've tried the following:

sudo ln -s /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/

From the comments to the original question, it seems that you have multiple versions of python installed and that pip just goes to the wrong version.

First, to know which version of python you're using, just type which python. You should either see:

which python /Library/Frameworks/Python.framework/Versions/2.7/bin/python 

if you're going to the right version of python, or:

which python /usr/bin/python 

If you're going to the 'wrong' version. To make pip go to the right version, you first have to change the path:

 export PATH=/Library/Frameworks/Python.framework/Versions/2.7/bin/python:${PATH} 

typing 'which python' would now get you to the right result. Next, install pip (if it's not already installed for this installation of python). Finally, use it. you should be fine now.
