Pip fails no matter what I try with "TypeError: unsupported operand type(s) for -=: 'Retry' and 'int'"

When I am trying to install something with pip on a brand new flashed SD card, it always fails. I know this has been posted before but I still haven't found an answer that has fixed it. I am defiantly not behind any kind of proxy. I have tried disabling ipv6. What else should I do?
Here is an example:

I am running high sierra,
which pip = /usr/local/bin/pip
python = 2.7.1
I am still new to python and this is my first time using it on this machine. I have googled a lot of different variations of this problem and am unable to figure out what I am doing wrong.
Sorry for such a simple question but any help would be appreciated. Thanks

You OpenSSL(not pyOpenSSL) is too old, you need to install an OpenSSL version that supports SNI.
