Python pip doesnt download/install source code from self-made package

Latelly, I've been worked on a Python Package, for learning purposes. I called this package Logmaster and, as it suggests, is a logging library. When I install the package (pip install logmaster), Only the dist-infos (in this case logmaster-1.0.1.dist-infos) are downloaded, not the actual source code.

Project structure:

Logmaster
├── LICENSE
├── README.md
├── src
│   ├── __init__.py
│   └── logger.py
├── pyproject.toml
└── setup.cfg

I tried to decompress the source code of the build (logmaster-0.1.0) to see if it was included, which it was, and to modify the content of the __init__.py file from from .logger import * to from . import *, and it didn't worked.

All the code is on github

Package on PyPi

A simpler solution, use a setup.py. (I changed the directory structure slightly):

$ git clone https://github.com/W1L7dev/Logmaster.git
$ cd Logmaster/
$ mv src/ logmaster/
$ echo "" > logmaster/__init__.py
$ rm pyproject.toml
$ rm setup.cfg
$ cat setup.py
from setuptools import setup

setup(
    name='logmaster',
    version='0.1.0',
    description='A simple logging library for Python',
    url='https://github.com/W1L7dev/logmaster',
    author='W1L7dev',
    author_email='w1l7dev@gmail.com',
    license='MIT',
    packages=['logmaster'],
    install_requires=[],
    classifiers=[
        'Programming Language :: Python :: 3.6',
    ],
)

With this it works as expected:

$ pip install -e .
Successfully installed logmaster-0.1.0
$ python
>>> from logmaster.logger import Logger
>>> Logger
<class 'logmaster.logger.Logger'>
>>> exit()
$ python3 -m build
Successfully built logmaster-0.1.0.tar.gz and logmaster-0.1.0-py3-none-any.whl
$ ls dist/
logmaster-0.1.0-py3-none-any.whl  logmaster-0.1.0.tar.gz
