Ruby on Rails: rails s or rails sever not working on mac

Here is my process

What I tried:

  • uninstalling & re-installing rails and railties
  • updates rails from 4.2.5 > 4.2.8
  • bundle install

As for the BigDecimal below, I have uninstalled it and re-installed the gem. I also changed the use of BigDecimal.new() to BigDecimal() as indicated when I researched this online.

/Users/nahomie/.rbenv/versions/2.6.3/lib/ruby/gems/2.6.0/gems/activesupport-4.2.8/lib/active_support/core_ext/object/duplicable.rb:111:in class:BigDecimal’: undefined method new' for BigDecimal:Class (NoMethodError)

**First I ran a bundle update, Results below: **

Post-install message from sass:

Ruby Sass has reached end-of-life and should no longer be used.

* If you use Sass as a command-line tool, we recommend using Dart Sass, the new
  primary implementation: https://sass-lang.com/install

* If you use Sass as a plug-in for a Ruby web framework, we recommend using the
  sassc gem: https://github.com/sass/sassc-ruby#readme
