How to install setuptools under a local python

Supposed you have a local python, which is used to built other staff. For example, buildozer will have this

src/.buildozer/android/platform/python-for-android/build/hostpython/Python-2.7.2

And this Python is missing setuptools for compiling, you need to install it under this Python. 

manual download the development version of setuptools from https://pypi.python.org/pypi/setuptools#downloads

move this setuptools into the Python directory

cd into the setuptools direcotry

find the executable for this python

run ../python.exe[where your python executable is] setup.py install

this will install setuptools under the local python. 

Note using easy_install setup tools only installs in your system not the local Python.  

How to update twisted Python

Source: http://stackoverflow.com/questions/1117255/how-to-update-the-twisted-framework

Try using virtualenv and pip (sudo easy_install virtualenv pip), which are great ways to avoid the dependency hell that you are experiencing.

With virtualenv you can create isolated Python environments, and then using pip you can directly install new packages into you virtualenvs.

Here is a complete example:

create fresh virtualenv, void of old packages, and install latest Twisted
virtualenv --no-site-packages twisted_env
pip -E twisted_env install -U twisted

#now activate the virtualenv
cd twisted_env
source bin/activate

#test to see you have latest Twisted:
python -c "import twisted; print twisted.__version__"

My Mac does not have -E option for pip. So I just run $ pip install -U twisted
