It looks like the issue is now solved using an external command called
brew rmdeps or
To install and use, issue the following commands:
$ brew tap beeftornado/rmtree $ brew rmtree <package>
See the above link for more information and discussion.
[EDIT] see the new command
brew autoremove in https://stackoverflow.com/a/66719581/160968
It appears that currently, there’s no easy way to accomplish this.
However, I filed an issue on Homebrew’s GitHub page, and somebody suggested a temporary solution until they add an exclusive command to solve this.
There’s an external command called
brew leaves which prints all packages that are not dependencies of other packages.
If you do a logical and on the output of
brew leaves and
brew deps <package>, you might just get a list of the orphaned dependency packages, which you can uninstall manually afterwards. Combine this with
xargs and you’ll get what you need, I guess (untested, don’t count on this).
EDIT: Somebody just suggested a very similar solution, using
join instead of
brew rm FORMULA brew rm $(join <(brew leaves) <(brew deps FORMULA))
