ruby/2.6.0/rubygems/dependency.rb:311:in `to_specs':   
Could not find 'ffi' (>= 1.3.0) among 81 total gem(s) (Gem::MissingSpecError)  

Checked in 'GEM_PATH=/Users/username/.rvm/gems/ruby-3.0.0:/Users/  
username/.rvm/rubies/ruby-3.0.0/lib/ruby/gems/3.0.0',

brew reinstall cocoapods

brew link --overwrite cocoapods
