python install package as sub-package of another package

I am developing a program ("homie") in python 2.7 with eclipse / pydev that contains several interfaces to external API providers. Those inherit a genric Interface-Class located inside the __init__.py inside homie.interfaces

All those interfaces now should be contained in sub-packages of homie.interfaces, such like homie.interfaces.foo and homie.interfaces.bar. Following the divide-and-conquer concept I created new projects for each interface implementation, containing the respective packages, such like foo, respectively bar.

The problem is now, that my setup.py script does of course not find the package myprogram.interfaces.foo during setup. Example: The worknet interface

#! /usr/bin/env python

from distutils.core import setup

setup(
    name='Worknet-DBs Interface',
    version='0.1-indev',
    author='Richard Neumann',
    author_email='[email protected]',
    packages=['homie.interfaces.worknet'],
    data_files=[],
    license=open('LICENSE.txt').read(),
    description='Interface implementation for the Worknet APIs',
    long_description=open('README.txt').read(),
)

Will produce:

[neumannr@neumann-homeinfo worknet.tmp]$ python ./setup.py install
running install
running build
running build_py
error: package directory 'homie/interfaces/worknet' does not exist
[neumannr@neumann-homeinfo worknet.tmp]$

If I specify just worknet instead of homie.interfaces.worknet it will of course install into the userbase instad of homie.interfaces. How can I tell the script to install the worknet package into homie.interfaces, so its path is homie.interfaces.worknet?

Point to your package directory by package_dir

package_dir parameter can provide information about where to find packages.

Pointing to existing worknet directory

Assuming, worknet directory is directly in your project root, you shall dd parameter package_dir into your setup call

package_dir = {'homie.interfaces': ''}

Moving package into subdirectory homie/interfaces

Another option is, you reorganize your code directories. E.g .you creat a path homie/interfaces/ and into it you move the existing worknet subdirectory.

In such a case, you would add

package_dir = {'homie.interfaces': 'homie/interfaces'}
