pip fails to install anything, error: invalid command 'egg_info'

Question

I recently downloaded python from their website in addition to the Python version that already comes with Mac OSX. This is when I began to have problems installing packages with pip.

sudo pip install -vvv pygoogle

Will output the following:

The directory '/Users/robot/Library/Caches/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

I have already tried all of the following, they just tell me the package setuptools is already installed.

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

Please note the following commands output:

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

And my .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

Solution

Try pip install --upgrade setuptools or easy_install -U setuptools

or

Download this file and execute python ez_setup.py

Downloading that file and running ez_setup.py solved it. Thanks

@KOHTPOJIEP there are two answers, you can try 2nd. Download that file and execute python ez_setup.py

[KOHTPOJIEP]

@Jameel Grand I've tried both of them. The first one falls with error "Can not execute file...". I've tried to fix it, but solutions I found didn't work neither. The second one just didn't make any effect.

Running pip install --upgrade setuptools then running easy_install PackageName has resolved it for me, where PackageName is the name of the package I was trying to install with pip initially but was failing.
