Answer 1

Your output says

Please install the sqlite3 adapter: `gem install activerecord-sqlite3-adapter` (sqlite3 is not part of the bundle. Add it to Gemfile.)

Have you got sqlite3 in your Gemfile?

If not - edit your "Gemfile" and add the line:

gem 'sqlite3'

Make sure to run "bundle install" after adding it.

Answer 2

answer is mentioned in your log, Please install the sqlite3 adapter, run the following command

gem install activerecord-sqlite3-adapter
