To help us debug your issue please explain:

• What you were trying to do (and why)

  Just tried to do brew leaves. But…

  $ brew leaves
  Error: No available formula with the name "gmp@4"
  

• What happened (include command output)

gmp@4 was listed in my brew list output. I did a brew uninstall gmp@4 after reading it got removed from brews core.

• What you expected to happen

Not seeing the error, but installed formulae that are not dependencies of another installed formula. My brew list:

Other things I tried to:

xcode-select --install
brew upgrade

… this was after reading the common issues section in the docs.

I also reinstalled Homebrew. Didn't fix the issue.

Out of desperation I tried to reinstall gmp@4:

$ brew install gmp@4
Error: No available formula with the name "gmp@4"
==> Searching for a previously deleted formula (in the last month)...
gmp@4 was deleted from homebrew/core in commit 8de2fabd2b:
  gmp@4: remove

To show the formula before removal run:
  git -C "$(brew --repo homebrew/core)" show 8de2fabd2b^:Formula/[email protected]

If you still use this formula consider creating your own tap:
  https://docs.brew.sh/How-to-Create-and-Maintain-a-Tap.html

I feel a bit like a noob now, not nowing how to fix this.

brew rm -f --ignore-dependencies cloog [email protected] [email protected] [email protected] [email protected] [email protected] [email protected] [email protected] [email protected] mpfr@2 [email protected]

and it should go away

Thanks. brew leaves works again.

I went through all the dependencies yesterday comparing them with other dependencies and dependents of other formulas and felt really lost after this because there where intersections in a lot of places. _(Basically I spend the whole day trying to remove formulas and get a clearer picture… I should have asked earlier.)_

The removal looked drastic on paper, but so far everything works like a charm. If not there's always brew install --only-dependencies <troublesome formula>. Thanks again.
