How to include and install local dependencies in setup.py in Python?

Question

I am creating a setup.py to distribute my application. This application has a number of dependencies which can be installed via pip, it also has some custom

Answer 1

Extending wiesiu_p's answer, you can install the dependency by linking to its source directory, which has its own setup.py.

Assume you have the source files of your dependency my-dependency, and the root of my-dependency has its own setup.py. In your application's setup.py:

setup(
  ...,
  install_requires=['other-dependency','my-dependency'],
  dependency_links=[
    # location to your my-dependency project directory
    ''.join(['file:\\', os.path.join(os.getcwd(), 'path', 'to', 'my-dependency#egg=my-dependency-1.0')])
  ]
)

Now if you run python setup.py install with your application's setup.py, it will install my-dependency.

Answer 2

There are several options that you can choose from:

1. Upload your package to some server, and provide the URL with dependency_links.
2. You could put your python package inside of your my_app package and link it with packages parameter, instead of using the wheel file.
3. A more hacky way would be to use the setuptools api, and install the package by yourself.

Answer 3

it is possible but not sure what setuptools version you should use. steps:

in setup.py

setup(
  ...,
  install_requires=['my-package'],
  dependency_links=[
    # location to your egg file
    os.path.join(os.getcwd(), 'deps', 'my_package-1.0.0-py3.5.egg')
  ]
)

important thing is that your location should not pass URL pattern test and egg file name should have structure <package_name_with_no_hyphens>-<version>-<py_version>.egg
