This happens when you fail to install GCC or xcode-select.

  1. Be sure you have xcode-select installed
xcode-select --install
  1. Be sure your version of puma installs
gem install puma -v 'x.y.z'
  1. If neither of these work try
bundle config build.puma --with-cflags="-Wno-error=implicit-function-declaration"

and then re-run bundle install

  • I had this problem when updating puma. running the command helped. – Yshmarov Nov 03 '21 at 11:25
  • note that there was a distinct root cause (fixed with #3) that I think affected XCode 12--- the answer for that is here, but it is NOT a duplicate because this question was filed after XCode 12 https://stackoverflow.com/questions/63187613/fail-to-bundle-install-puma-4-3-5-or-gem-puma-with-ruby-2-6-6-on-macos-10-15-6 – Jason FB Apr 16 '22 at 13:33

I faced the same issue when i was trying to install gem for Jekyll.

xcode-select --install

This solved the issue.

I downloaded and installed "Command Line Tools for Xcode 13" from here https://developer.apple.com/download/all/ and it solved the issue for me. xcode-select --install said it was going to take over an hour.
