NameError: name 'execfile' is not defined

Using python 3 I cannot install nupic_studio. I get the following:

pip3 install nupic_studio
Defaulting to user installation because normal site-packages is not writeable

  note: This error originates from a subprocess, and is likely not a problem with pip.
