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

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.

update path with correct python
uninstall pip using python -m pip uninstall pip setuptools
restart windows didn't work until a restart
#!/usr/bin/python
# EASY-INSTALL-ENTRY-SCRIPT: 'pip==1.5.6','console_scripts','pip'
__requires__ = 'pip==1.5.6'
import sys
from pkg_resources import load_entry_point
if __name__ == '__main__':
sys.exit(
load_entry_point('pip==1.5.6', 'console_scripts', 'pip')()
So if you got the same in MacOS, pip would always use /usr/bin/python.
But this is a default. You can still provide the version of python you want either by editing the file or by using python explicitly.
If which python returns /usr/bin/python then something went wrong when you installed your own version. If it is /Library/Frameworks/Python.framework/Versions/2.7/bin/python, you can directly call:
sudo python `which pip` install scikit-learn --upgrade
However, chances are high that it won't work. The reason is that sudo is resetting all your environment variables. To make it work, the easiest would be to use:
sudo -E pip install scikit-learn --upgrade
sudo -E python `which pip` install scikit-learn --upgrade
depending on your setup.
2 - What you should do
pip was not thought of as something that root should execute. The actual best way to use it is to install a local, non-root, python version. You just have to make sure that you use it by default by setting up the correct environment variables (such as PATH on Linux) and then install pip without sudo using that python version.
An even better way would be to setup virtualenvs from your root install.
This way, you can install/update whatever you want without root privileges and never bother again about why sudo pip is not working. You would also avoid to provide root privileges to whatever is on Pypi and that would warrant that you don't mix system libs with your own.

I totally agree with the guys, it's better to use virtualenv so you can set a custom environment for every project. It ideal for maintenance because it's like a different world for every project and every update of an application you make won't interfere with other projects.
Here you can find a nutshell of virtualenv related to installation and first steps.

download pip at https://pypi.python.org/pypi/pip (tar)
unzip tar file
cd to the file’s directory
sudo python2.7 setup.py install
You could just change the shebang line. I do this all the time on new systems.
If you want pip to install to a current version of Python installed just update the shebang line to the correct version of pythons path.
For example, to change pip (not pip3) to install to Python 3:
#!/usr/bin/python
#!/usr/bin/python3
Any module you install using pip should install to Python not Python.
Or you could just change the path.

I've tried this and it worked for me,
curl -O https://files.pythonhosted.org/packages/c0/4d/d2cd1171f93245131686b67d905f38cab53bf0edc3fd1a06b9c667c9d046/boto3-1.14.29.tar.gz
tar -zxvf boto3-1.14.29.tar.gz
cd boto3-1.14.29/
Replace X with your required python interpreter, for mine it was python3
sudo pythonX setup.py install
In Windows it happened to me when I upgraded the pip version from 23.0.1 to 23.2.1. This was in Python 3.10.11.
To fix it I just downgraded to pip back to 23.0.1
python -m pip install pip==23.0.1
python -V
then install the correct pip. You might already have intall in that case try to use:
pip-2.5 install ...
pip-2.7 install ...
or for those of you using macports make sure your version match using.
port select --list pip
then change to the same python version you are using.
sudo port select --set pip pip27
Hope this helps. It work on my end.
