Hi !
I wanted to reinstall Gtk because I got an issue with empty windows. But now Cairo does not want to build.
I tried to update,upgrade, update-reset, rm, … Homebrew.
There is a topic on brew "forum"about that [brew topic](https://discourse.brew.sh/t/undefined-method-uses-from-macos/5232) but there doesn’t seem to have a solution.
I don’t know what to do.
Thank you for your help !

Building Cairo has been a problem since a few months, I’m not sure there’s a clear solution yet:
[https://github.com/JuliaPackaging/Homebrew.jl/issues/257](https://github.com/JuliaPackaging/Homebrew.jl/issues/257)
[https://github.com/JuliaGraphics/Cairo.jl/issues/271](https://github.com/JuliaGraphics/Cairo.jl/issues/271)
I broke my Gtk installation last week, and the only thing I could do was copy an older version of my Homebrew folder (which contains all the binary dependency) to restore it to a working state.
Maybe try the master branch of Homebrew:
