Python packages distribution

Currently python options for code distribution  are bit messy as described here.   I spent some time to find right way how to create setup script, which will install external dependencies,   so here is the recipe for python3:

Create virtual virtual environment for your project:

virtualenv -p /usr/bin/python3 .

Then create file – two important things:

Import setup function from setuptools,   this l enables to specify dependencies, which should be installed  automatically by pip or easy_setup.

It is important that install_requires keyword is  included. Also note different syntax of version requirements  – requires vs install_requires . (requires and provides are probably not necessary ).

Test files,  readme, license  files etc.   specify them in file in root of distribution – something like this:

Once all code is ready you can create distribution with command:

python sdist

This will create packed distribution in dist subdirectory  and then you can try to install in another virtual environment by:

pip install path/to/dist/packageX-1.0.0.tar.gz
