I can't upgrade pip on my raspberry pi

I want to install simpleaudio but can't upgrade or install anything with pip, here's what it gives me:

Downloading/unpacking pip from https://pypi.python.org/packages/9c/32/004ce0852e0a127f07f358b715015763273799b d798956fa930814b60f39/pip-8.1.2-py2.py3-none-any.whl#md5=0570520434c5b600d89ec95393b2650b Downloading pip-8.1.2-py2.py3-none-any.whl (1.2MB): 1.2MB downloaded Installing collected packages: pip Found existing installation: pip 1.5.6 Not uninstalling pip at /usr/lib/python2.7/dist-packages, owned by OS Can't roll back pip; was not uninstalled Cleaning up...

I'm using Rasbian with NOOBS if that help figuring this out. I've just started studying programming so I have no clue what I need to do since using the guides results to above, so please explain this to an idiot.
