setuptools_scm raises AssertionError: own dev numbers are unsupported

Question

I have been using these two arguments in the setup.py for a while without any problems.

use_scm_version={"local_scheme": "no-local-version",},
setup_requires=["setuptools_scm"],

Although I have not made any changes on the setup.py, today I started having this exception below.

AssertionError: own dev numbers are unsupported

It happens when I call python setup.py. I suspect it is due to a change the maintainers of setuptools made recently.

The full error goes like this:

module_name/.eggs/setuptools_scm-4.1.2-py3.7.egg/setuptools_scm/version.py", line 229, in _bump_dev
    assert tail == "0", "own dev numbers are unsupported"
AssertionError: own dev numbers are unsupported

I tried changing the setup.py with this

use_scm_version=True,
setup_requires=["setuptools_scm"],

Still the exception is raised. What might be the problem here?
Thanks in advance!

When you encounter this error, check the git tags with the git tag -l command.

If a tag is containing dev in its name such as 0.1.dev37 then delete it using git tag -d 0.1.dev37.
