How to install a dependency from a submodule in Python?
setuptools.find_packages()
is able to discover submodules
Your setup.py
should look like
from setuptools import setup, find_packages
setup(
packages=find_packages(),
# ...
)
Create a package for mysubmodule
with its own setup.py
and let the top-level package depend on that package in its setup.py
. This means you only need to make the packages / dependencies available and run python setup.py install
on the top-level package.
The question then becomes how to ship the dependencies / packages to your customers but this can be solved by putting them in a directory and configuring setup.py
to include that directory when searching for dependencies.
The alternative is to "vendor" mysubmodule
which simply means including it all in one package (no further questions asked) and having one python setup.py install
to install the main package. For example, pip
vendors (includes) requests
so it can use it without having to depend on that requests
package.
