[Pip] Packaging and distributing project with git and pip

1- make the project "pip compatible"

in your project directory: nano setup.py

from setuptools import setup

setup( 

   name='testapp', 

   version='0.1', 

   description='A test application !', 

   url='http://github.com/testappli', 

   author='an_author', 

   author_email='author@author', 

   license='MIT', 

   packages=['xyz'], 

   install_requires=['cherrypy'], 

   zip_safe=False

)

mkdir xyz (the package)

cd xyz

nano utils.py

def print_hello(): 

   print("print_hello called")

nano __init__.py

#empty file

2- how to install our project with pip from our private repository

retrieve project with pip: 
pip install https://github.com/user/repository/archive/branch.zip 

which becomes for django master: 
pip install https://github.com/django/django/archive/master.zip 

for django stable/1.7.x: 
pip install https://github.com/django/django/archive/stable/1.7.x.zip 

With BitBucket it's about the same predictable pattern: 
pip install https://bitbucket.org/izi/django-admin-tools/get/default.zip

for a private Bitbucket repository:
pip install git+https://bitbucket.org/<bitbucket_username>/<repo_name>.git
