macos - Python pip installation on Mac is not working

Question

I have a Macbook Air and want to install pip. I have the updated python version. I follow all the instructions but I cannot install any packages.

I have been researching for more than 1 hour and looking at many articles and questions but I cannot figure it out.

This is what is displayed on my Terminal when I try to install pip, and then install a package called beautifulsoup:

arnau@MacBook-Air-de-Arnau ~ % python --version
Python 2.7.16
arnau@MacBook-Air-de-Arnau ~ % curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

I don't understand what is happening or what I should do to solve the error.
