Hi, I'm modifying a python project which uses setuptools for installation. The project installs an entry point as such: setup_args["entry_points"] = { "console_scripts": ["w1thermsensor = w1thermsensor.cli:cli [CLI]"] } where [CLI] is a reference to an extra_requires entry. This entry looks like this: extras_require=dict(CLI="click>=7.0") With these two lines, the current behavior is that the w1thermsensor entry point is *always* installed when "setup.py install" is invoked, but the entry point will cause an error if its dependencies are not available. I would like to change the behavior, so that the entry point is *not installed* if the extra dependencies are not available (and perhaps also show a warning, indicating that this entry point has not been installed). How can I do this? Cheers, Jonatan
