brew or pip - install credstash - errors - No named formulae found in taps / OSErr six-1.4.1-py2.7.egg-info operation not permitted - macos

Question

Getting the following error on my Mac Terminal window.
$ pip --version
pip 6.1.1 from /Library/Python/2.7/site-packages (python 2.7)
Python version is 2.7.10
While trying to install credstash using brew, I'm getting the following error.
$ `which python` --version && brew update && brew install credstash
Python 2.7.10
Already up-to-date.
Error: No available formula with the name "credstash"
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching taps...
Error: No formulae found in taps.
Got the similar error, when I tried to install pip3 using brew.
Tried installing credstash from pip but that errored out as well.

You are using pip version 6.1.1, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

DEPRECATION: Uninstalling a distutils installed project (six) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.

To get latest pip, as pip is provided via python on macOS, if I try to install python using brew, I'm getting the following, poking into it how I can remove Xcode first:
$ brew install python
Error: Your Xcode (5.0.2) is too outdated.
Please update to Xcode 8.2 (or delete it).
Xcode can be updated from the App Store.
$ pip --version
pip 6.1.1 from /Library/Python/2.7/site-packages (python 2.7)
As I thought I have an older pip version, I download this file:
$ wget https://bootstrap.pypa.io/get-pip.py && sudo python get-pip.py
Which successfully installed a newer version of pip. Now showing:
$ pip --version
pip 9.0.1 from /Library/Python/2.7/site-packages (python 2.7)
Retried doing pip install credstash but still getting the same error (with or without sudo).

Answer 1

I tried the following to get credstash installed.
Downloaded Python3 Mac binary from here.
https://www.python.org/ftp/python/3.5.2/python-3.5.2-macosx10.6.pkg
Installed the .pkg file GUI way.
Opened a Terminal window in Mac.

If you're trying to install to system Python then you need sudo. If you want to just play around, look into creating a virtualenv and install there. http://docs.python-guide.org/en/latest/dev/virtualenvs/
