Could not load the 'postgres' Active Record adapter

[LongLonghaoran]

I meet this error when my database.yml has been configured to use postgresql.

[LongLonghaoran]

And i found some code here

      def default_sequel_adapter_options(world)
        db_config            = ::ActiveRecord::Base.configurations.to_h[::Rails.env]
        db_config['adapter'] = db_config['adapter'].gsub(/_?makara_?/, '')
        # what is this mean?
        db_config['adapter'] = 'postgres' if db_config['adapter'] == 'postgresql'
        db_config['max_connections'] = calculate_db_pool_size(world) if increase_db_pool_size?

        if db_config['adapter'] == 'sqlite3'
          db_config['adapter'] = 'sqlite'
          database = db_config['database']
          unless database == ':memory:'
            # We need to create separate database for sqlite
            # to avoid lock conflicts on the database
            db_config['database'] = "#{File.dirname(database)}/dynflow-#{File.basename(database)}"
          end
        end
        db_config
      end

Could you paste the exact error you're getting, ideally with a stack trace?

Your Gemfile lists the gem puma (~> 5.1) more than once.
You should probably keep only one of them.
Remove any duplicate entries and specify the gem only once.
While it's not a problem now, it could cause errors if you change the version of one of them later.
