How to make fail when not tag is available?

If you do a git clone with a limited fetch depth so that you don't end up with any tags in your repository, setuptools_scm will happy generate a very confusing version number. I would like it to instead fail loudly (and tell the person how to fix their git repository to have a tag).

Any idea how I can do this? Thanks!

PS This would probably be a much better default option for setuptools_scm.
