How to remove Homebrew formula/keg that no longer exists?

问题

I'm trying to remove extempore but I get the following:

$ brew uninstall extempore Error: No available formula with the name "extempore-llvm"

Trying to uninstall extempore-llvm

$ brew uninstall extempore-llvm Error: No such keg: /usr/local/Cellar/extempore-llvm

Adding --force does not do anything.

How do I remove this keg/formula completely? Brew can't uninstall/install/reinstall anything while this is an issue.

回答1:

Remove /usr/local/Cellar/extempore-llvm manually, then execute brew prune.
