Fix versioning #3

Closed pombredanne closed 3 years ago

pombredanne commented 3 years ago

Building a wheel or sdist from a tarball that is NOT a git checkout (e.g. without .git metadata directory) ends up having a 0.0.0 version. We need a fallback from setuptools_scm

Here is the problem:

$ wget https://github.com/nexB/typecode/archive/v21.1.21.tar.gz
$ tar -xf typecode-21.1.21.tar.gz 
$ python setup.py bdist_wheel

Make sure you're either building from a fully intact git repository or PyPI tarballs. Most other sources (such as GitHub's tarballs, a git checkout without the .git folder) don't contain the necessary metadata and will not work.

For example, if you're using pip, instead of https://github.com/user/proj/archive/master.zip use git+https://github.com/user/proj.git#egg=proj

This is now handled with the latest skeleton using setuptools_scm fallback_version
