> If your package is a counterexample ( `setup.py install` works but `setup.py bdist_wheel` doesn’t), please share details!

`pip install` and `setup.py bdist_wheel` treat `install_requires` differently. See the discussion at [Install install\_requires before running python setup.py bdist\_wheel · Issue #6193 · pypa/pip · GitHub](https://github.com/pypa/pip/issues/6193) and [Support for build-and-run-time dependencies](https://discuss.python.org/t/support-for-build-and-run-time-dependencies/1513)
