If a version specifier was allowed for direct references, this would the same thing: it would be the installer job to check that the provided link matches the provided version specifier, just like it should be checking that the package name matches ;). If the direct references was inconsistent, the installer could print a warning or abort the installation. Currently with pip 19, an inconsistent name in a direct reference only produces a warning. With a setup.py containing from setuptools import setup setup(name='foo', version='1', install_requires=['toto @ https://files.pythonhosted.org/packages/06/18/fa675aa501e11d6d6ca0ae73a101b2f3571a565e0f7d38e062eec18a91ee/mccabe-0.6.1.tar.gz' ]) "pip install . --no-cache-dir" ends up (unhappily & with a few warnings) with mccabe 0.6.1 installed.
