I was getting a similar error on my macos while trying to use the nokogiri gem.

Turns out the gem was installed for the incorrect platform, as the error message says.

 > gem list | grep nokogiri 
 nokogiri (1.13.1 x86_64-darwin, 1.10.1, 1.6.2.1)

I fixed this by uninstalling the gem

gem uninstall nokogiri --version 1.13.1

and then reinstalling it with the correct platform.

gem install nokogiri --user-install --platform arm64-darwin

If you see this issue with the Nokogiri gem while trying to start your Rails app, remove

nokogiri (1.13.6-arm64-darwin)
      racc (~> 1.4)

from your Gemfile and do a bundle install
