byebug: Byebug install error

l am currently trying to install byebug with my rails project and keep getting this error

An error occurred while installing byebug (9.0.5), and Bundler cannot continue.
Make sure that `gem install byebug -v '9.0.5'` succeeds before bundling.

Any idea why this would be?

For the people coming here from search engines… Installing older versions of byebug (in my case, 4.0.5) required the installation of llvm@11 and then

export CC=/usr/local/opt/llvm@11/bin/clang
export CCX=/usr/local/opt/llvm@11/bin/clang

Oh, the joys of legacy development.

I also encountered this error (Apple M1, Monterey), and it worked after setting export CC=clang.

I got it working with below steps on big sur: Reinstall commandline tools

sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install

Install llvm

brew install llvm

Set cc and ccx to llvm from homebrew export CC=/usr/local/opt/llvm/bin/clang export CCX=/usr/local/opt/llvm/bin/clang

I’m not a Mac user, but looks like the only solution is to use:

CC=llvm-gcc gem install byebug -v '9.0.5'
