Python error “ImportError: No module named”

Question

Python is installed in a local directory.

My directory tree looks like this:

(local directory)/site-packages/toolkit/interface.py

Answer 1

If you are using a setup script/utility (e.g. setuptools) to deploy your package, don't forget to add the respective files/modules to the installer.

When supported, use find_packages() or similar to automatically add new packages to the setup script. This will absolutely save you from a headache, especially if you put your project aside for some time and then add something later on.

import setuptools

setuptools.setup(
    name="example-pkg",
    version="0.0.1",
    author="Example Author",
    author_email="author@example.com",
    description="A small example package",
    packages=setuptools.find_packages(),
    classifiers=[
        "Programming Language :: Python :: 3",
        "Operating System :: OS Independent",
    ],
    python_requires='>=3.6',
)
