Error installing B2 Command Line on MacOS High Sierra

The failure comes from the setup.py egg_info step when pip builds the b2-1.4.0 source tarball under the system Python 2.7 on macOS, which reports that setuptools 20.2 or later is required. Start by checking the packaging metadata and setup.py in the repository for the setuptools requirement and whether Python 2.7 is still supported. Done means a clean install path on that platform, or a documented requirement that explains the failure.

I'm not very familiar with command line use or terminal, just enough to cut/paste from instructions, but since I'm going to add B2 to my account I thought tje command line tool should be added to my account. I followed the installation instructions on: https://www.backblaze.com/b2/docs/quick_command_line.html
down through the "ignore-installed" work around but still get an error.

What should I do now? If I upgraded to Mojave before installing would that solve it?

Here is a transcript from Terminal when trying to install B2 command line tool:
