Packaging Exception

[marcossantiago]

Hi there,

Thanks for the cool project! I really appreciate it.

I have been testing on a small python project, but I am facing some issues when installing the package that uses dunamai for Version control. Is this supported or am I missing something ?

This is the setup.py:

from setuptools import find_packages, setup
from dunamai import Version, Style

setup(
    name="add_custom_dataplatform",
    version=Version.from_any_vcs().serialize(metadata=False, style=Style.SemVer),
    packages=find_packages()
)

It works great when I create the package or run the commands locally:

$ python setup.py sdist
...
Creating tar archive
removing 'add_custom_dataplatform-0.0.0.post40' (and everything under it)

But fails when I try to install it

$ pip install add_custom_dataplatform-0.0.0.post40.tar.gz

Please the installation works fine if I set a static version.

One option would be to use wheels instead of an sdist, since the wheel will include the raw version rather than having to re-execute the code to get it.

If you need sdists, then it would probably be best to write an external script that dumps the dynamic version into setup.py (hard-coded as a string) and then reverts it after packaging.

Makes sense. Thank you @mtkennerly. Appreciate.
