I am trying to install a python 3 library on a raspberry pi 3 running Raspbian-Jessie.
sudo pip3 install LIBRARY However, regardless of what library I try to install, I am getting this error:

I already tried installing multiple libraries (dlib, numpy, keras) and the result is the same. I also tried:
sudo apt-get update sudo apt-get upgrade and still no luck.
