Ich habe bereits versucht, alle der folgenden, die Sie gerade sagen Sie mir das Paket setuptools ist bereits installiert.

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

Bitte beachten Sie die folgenden Befehle Ausgabe:

where python
/Library/Frameworks/Python.framework/Versions/2.7/bin/python
/usr/local/bin/python

which python
/Library/Frameworks/Python.framework/Versions/2.7/bin/python

where pip
/Library/Frameworks/Python.framework/Versions/2.7/bin/pip
/usr/local/bin/pip

which pip
/Library/Frameworks/Python.framework/Versions/2.7/bin/pip

echo $SHELL
/bin/zsh

Und meine .zprofile:

# Setting PATH for Python 2.7
# The orginal version is saved in .zprofile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/2.7/bin:${PATH}"
export PATH
