I ran tests for 2.0.1 sdist and it failed:
____________________ ERROR collecting test/test_linkify.py _____________________
ImportError while importing test module '$(BUILD_DIR)/test/test_linkify.py'.
Hint: make sure your test modules/packages have valid Python names.
Traceback:
/usr/lib/python3.9/importlib/__init__.py:127: in import_module
return _bootstrap._gcd_import(name[level:], package, level)
test/test_linkify.py:7: in <module>
from .utils import read_fixture_file
E ImportError: attempted relative import with no known parent package
The sdist is apparently missing some files in the test directory.
