Issues found when installing on OSX 10.15, Catalina.

Wrong version of the bcrypt-gem.

An error occurred while installing bcrypt-ruby (3.0.0).

Building native extensions. This could take a while... ERROR: Error installing bcrypt-ruby: ERROR: Failed to build gem native extension. gem 'bcrypt-ruby', '~> 3.0.0'

The 3.0.0 version of this bcrypt-ruby gem is depending on 32-bit application support. Catalina has removed support for 32-bit.

Install the a later version of the bcrypt-gem, 3.1.0:

Update the Gemfile and run bundle install gem 'bcrypt-ruby', '~> 3.1.0'

Installing the Thin HTTP server.

Downgrade the version of V8, javascript engine, that the Thin gem depends on.
