An error occurred while installing byebug (5.0.0), and Bundler cannot continue. Make sure that gem install byebug -v '5.0.0' --source 'https://rubygems.org/' succeeds before bundling.

Answer 1

Take a look here https://github.com/deivid-rodriguez/byebug/issues/280

brew install llvm@11

export CC=/usr/local/opt/llvm@11/bin/clang
export CCX=/usr/local/opt/llvm@11/bin/clang
gem install byebug -v '5.0.0'

maybe something like this will fix the problem?

Or something like this https://github.com/ruby/ruby/pull/4504#issuecomment-929696628

gem install byebug -v '5.0.0' -- --with-cppflags="-Wno-compound-token-split-by-macro"
