Virtualenv is your friend

Even if you want to add a package to your primary install, it's still best to do it in a virtual environment first, to ensure compatibility with your other packages. However, if you get familiar with virtualenv, you'll probably find there's really no reason to install anything in your base install.

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

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

1 - Something that might work  The pip executable is actually a Python script   By default it contains  on Linux       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   or   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

Make sure you pip version matches your python version   to get your python version use   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

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   To      usr bin python3   Any module you install using pip should install to Python not Python    Or you could just change the path

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
