It looks like this is an issue with the version of Python shipped with El Capitan [1]. Apple don’t want to allow folks to mess up the Python that ships with OS X since it is used by the operating system. But it is kinda annoying, right?
I think you could try a few different approaches to solving this problem:
1) Upgrade to Sierra and see if the problem goes away.
2) Install a new Python that you can use (pymarc works with Python3). I would recommend installing Python3 with homebrew, but you can also download an installer.
3) Start using pipenv to manage a local python environment. You could install pymarc into this environment and use it for whatever development you are doing.
4) Follow the instructions at [1] to try to install pymarc without upgrading six: pip install twarc --upgrade --ignore-installed six
Personally I would probably go with 1 first because it’s good to keep the operating system up to date. But 4) might be the best thing to try if you are looking for a quick solution. 2 and 3 are more about how to do development with Python, but perhaps you may not be interested in diving into those things right now.
If you have any questions about any of these options please ask!
