I have created a package with the following structure in the dev branch (not merging to main until I verify the package installs correctly):

mypackage
|
|-- __init__.py
|-- setup.py
|-- requirements.txt
|-- module.py
|-- subpackage_one
    |
    |-- __init__.py
    |-- module_ab.py
        |-- class_aba
        |-- class_abb
    |-- module_ac.py
        |-- function_aca

|-- subpackage_two
    |
    |-- __init__.py
    |-- module_ba.py
        |-- function_baa

Additional information:

• The __init__.py files at root and in subpackage__two are both empty
• The __init__.py file in subpackage_one contains some additional initialization in the form of from mypackage.subpackage_one.module_xx import class_xxx (or function_xxx)
• I am installing the package via pip install git https://github.com/organization/repo.git@dev
• If I am in the root directory of the package, I can import the submodules as expected
• The setup.py file is:

import setuptools

with open("README.md", "r", encoding="utf-8") as fh:
    long_description = fh.read()

setuptools.setup(
    name='mypackage',
    version='0.0.2',
    author='author1, author2',
    author_email='author1_email, author2_email',
    description='My Package',
    long_description=long_description,
    long_description_content_type="text/markdown",
    url='https://github.com/organization/repo',
    packages=['mypackage'],
    install_requires=['requests'],
)

• When I run the following snippet:

import pkgutil
for i in pkgutil.iter_modules(mypackage.__path__):
    print(i)

I see:

ModuleInfo(module_finder=FileFinder('/path/to/package/mypackage'), name='module', ispkg=False)

And indeed, the subpackages are not in the mypackage folder.

How can I get the subpackages to install along with the package?

CodePudding user response：

Your issue might be the packages parameter. It needs to be supplied with every module or 'package'.

setuptools has a nice function to find them, use it like this: packages=setuptools.find_namespace_packages(),
