Fixing Ruby Gem Issues

-
To fix the error:
/opt/metasploit/vendor/bundle/ruby/2.7.0/gems/activerecord-4.2.11.1/lib/active_record/connection_adapters/abstract_adapter.rb:84: warning: deprecated Object#=~ is called on Integer; it always returns nil

Just open
/opt/metasploit/vendor/bundle/ruby/2.7.0/gems/activerecord-4.2.11.1/lib/active_record/connection_adapters/abstract_adapter.rb
in a text editor and change line 84 from
if config =~ SIMPLE_INT"
to
if config.to_i.to_s == config
