i have tried of following, tell me package setuptools installed.

sudo pip install setuptools sudo pip install [--upgrade] setuptools easy_install [-u] setuptools

please note following commands output:

where python /library/frameworks/python.framework/versions/2.7/bin/python /usr/local/bin/python  python /library/frameworks/python.framework/versions/2.7/bin/python  pip /library/frameworks/python.framework/versions/2.7/bin/pip /usr/local/bin/pip  pip /library/frameworks/python.framework/versions/2.7/bin/pip  echo $shell /bin/zsh

and .zprofile:

# setting path python 2.7 # orginal version saved in .zprofile.pysave path="/library/frameworks/python.framework/versions/2.7/bin:${path}" export path

try pip install --upgrade setuptools or easy_install -u setuptools

or

download this file , execute python ez_setup.py
